(a) The support (range) of each random variable M₁, M₂, and M₃ depends on the specific values and transitions of the stock price process.

In the 3-period binomial model, the stock price process can take different values at each period based on up and down movements. Let's denote the up movement factor as u and the down movement factor as d.

The support of M₁:

M₁ can take two possible values:

If the stock price goes up in the first period, M₁ = S₁ * u.

If the stock price goes down in the first period, M₁ = S₁ * d.

The support of M₂:

M₂ can take three possible values:

If the stock price goes up in both the first and second periods, M₂ = S₁ * u * u.

If the stock price goes up in the first period and down in the second period, M₂ = S₁ * u * d.

If the stock price goes down in the first period and up in the second period, M₂ = S₁ * d * u.

If the stock price goes down in both the first and second periods, M₂ = S₁ * d * d.

The support of M₃:

M₃ can take four possible values:

If the stock price goes up in all three periods, M₃ = S₁ * u * u * u.

If the stock price goes up in the first and second periods, and down in the third period, M₃ = S₁ * u * u * d.

If the stock price goes up in the first period, down in the second period, and up in the third period, M₃ = S₁ * u * d * u.

If the stock price goes down in the first and second periods, and up in the third period, M₃ = S₁ * d * u * u.

If the stock price goes up in the first period, down in the second period, and down in the third period, M₃ = S₁ * u * d * d.

If the stock price goes down in the first period, up in the second period, and up in the third period, M₃ = S₁ * d * u * u.

If the stock price goes down in the first and second periods, and down in the third period, M₃ = S₁ * d * d * u.

If the stock price goes down in all three periods, M₃ = S₁ * d * d * d.

(b) The probability distribution (p.m.f.) of M₃ can be determined by considering the probabilities of each possible value in the support of M₃. The probabilities are derived from the probabilities of up and down movements at each period. Let's denote the probability of an up movement as p and the probability of a down movement as 1 - p.

(c) Conditional expectations:

(i) E[M₂ | S₁]:

The conditional expectation of M₂ given the value of S₁ can be calculated by considering the possible values of M₂ and their respective probabilities. Using the probabilities of up and down movements, we can determine the expected value of M₂ conditioned on S₁.

(ii) E[M₃ | σ(S₁)]:

The conditional expectation of M₃ given the value of S₁ and the information of the up and down movements can also be calculated by considering the possible values of M₃ and their respective probabilities. The probabilities of up and down movements at each period are used to determine the expected value of M₃ conditioned on S₁.

The specific calculations for the conditional expectations require the values of u, d, p,

The trace of the linear transformation L on V, defined by L(X) = (AX + XAY), can be calculated as the trace of the matrix A. In this case, since A is a 2x2 diagonal matrix with diagonal entry 2, the trace of L is 4.

The linear transformation L on V is defined by L(X) = (AX + XAY), where X is a 2x2 matrix and A is a diagonal matrix. To calculate the trace of L, we need to find the trace of the resulting matrix when L is applied to X.

Let's consider an arbitrary 2x2 matrix X:

X = | a b |

| c d |

We can now apply L to X:

L(X) = (AX + XAY)

= AX + XA*Y

To calculate the product A*X, we multiply each entry of A by the corresponding entry of X:

A*X = | 2a 0 |

| 0 2d |

Similarly, the product XAY is obtained by multiplying each entry of X by the corresponding entry of A*Y:

XAY = | a b | * | 2b 0 |

| c d | | 0 2c |

Multiplying these matrices and summing the entries, we get:

L(X) = | 2a + 2b² 2b² |

| 2c 2c + 2d² |

The trace of a matrix is the sum of its diagonal entries. In this case, the diagonal entries of L(X) are 2a + 2b² and 2c + 2d². So the trace of L(X) is:

Trace(L(X)) = 2a + 2b² + 2c + 2d²

Since the matrix A is diagonal with diagonal entry 2, the trace of A is 2. Therefore, the trace of the linear transformation L is:

Trace(L) = 2 + 2 = 4 Hence, the trace of L is 4.

The LCM of A, B, and C is the product of all these values 120764100.

To determine the least common multiple (LCM) of A, B, and C, we can use the prime factorization method, which involves multiplying each of the prime factors of A, B, and C the greatest number of times it occurs in any of them. Then, we have to take the product of the highest exponent value from each prime factor.

Example: The prime factorization of 45 is 3² × 5, and the prime factorization of 75 is 3 × 5². Multiplying both gives us the LCM: 3² × 5² = 225. Therefore, the LCM of 45 and 75 is 225.

There are infinitely many values of [tex]\( c \)[/tex] that satisfy the equation  [tex]\( f'(c) = 7 \)[/tex] in the conclusion of the Mean Value Theorem for the function [tex]\( f(x) = 5x + 2x - 3 \)[/tex]  on the interval [tex]\([-3, -1]\)[/tex]

To apply the Mean Value Theorem, we need to check if the given function, [tex]\( f(x) = 5x + 2x - 3 \)[/tex], satisfies the necessary conditions.

These conditions are:

1. [tex]\( f(x) \)[/tex] must be continuous on the closed interval [tex]\([-3, -1]\)[/tex].

2. [tex]\( f(x) \)[/tex] must be differentiable on the open interval [tex]\((-3, -1)\)[/tex].

Let's check if these conditions are met:

1. Continuity: The function [tex]\( f(x) = 5x + 2x - 3 \)[/tex] is a polynomial, and polynomials are continuous for all real numbers. Therefore,[tex]\( f(x) \)[/tex] is continuous on [tex]\([-3, -1]\)[/tex].

2. Differentiability: The function [tex]\( f(x) = 5x + 2x - 3 \)[/tex] is a polynomial, and all polynomials are differentiable for all real numbers. Therefore, [tex]\( f(x) \)[/tex] is differentiable on [tex]\((-3, -1)\)[/tex].

Since both conditions are satisfied, we can apply the Mean Value Theorem.

The Mean Value Theorem states that if a function [tex]\( f \)[/tex] is continuous on the closed interval [tex]\([a, b]\)[/tex] and differentiable on the open interval [tex]\((a, b)\)[/tex], then there exists a number [tex]\( c \)[/tex] in [tex]\((a, b)\)[/tex] such that:

[tex]\[ f'(c) = \frac{{f(b) - f(a)}}{{b - a}} \][/tex]

In this case, [tex]\( a = -3 \)[/tex] and [tex]\( b = -1 \)[/tex].

We need to obtain the value or values of  [tex]\( c \)[/tex] that satisfy the equation [tex]\( f'(c) = \frac{{f(b) - f(a)}}{{b - a}} \)[/tex].

First, let's calculate [tex]\( f(b) \)[/tex] and [tex]\( f(a) \)[/tex]:

[tex][ f(-1) = 5(-1) + 2(-1) - 3 = -5 - 2 - 3 = -10 \][/tex]

[tex][ f(-3) = 5(-3) + 2(-3) - 3 = -15 - 6 - 3 = -24 \][/tex]

Now, let's calculate [tex]\( f'(x) \)[/tex]:

[tex]\[ f'(x) = \frac{{d}}{{dx}} (5x + 2x - 3) = 5 + 2 = 7 \][/tex]

We can set up the equation using the Mean Value Theorem:

[tex]\[ 7 = \frac{{-10 - (-24)}}{{-1 - (-3)}} = \frac{{14}}{{2}} = 7 \][/tex]

The equation is satisfied, which means there exists at least one [tex]\( c \)[/tex] in [tex]\((-3, -1)\)[/tex] such that [tex]\( f'(c) = 7 \)[/tex].

However, since the derivative of the function [tex]\( f(x) = 5x + 2x - 3 \)[/tex] is a constant (7), the value of [tex]\( c \)[/tex] can be any number in the interval [tex]\((-3, -1)\)[/tex].

To determine the fraction of the time Player I should play Row B, we can use the concept of mixed strategies in game theory.

Player I aims to maximize their expected payoff, considering the probabilities they assign to each of their available strategies.

In this case, we have the following payoff matrix:

      α     B

LA   -7     3

B      8    -2

To find the fraction of the time Player I should play Row B, we need to determine the probability, denoted as p, that Player I assigns to playing Row B.

Let's denote Player I's expected payoff when playing Row LA as E(LA) and the expected payoff when playing Row B as E(B).

E(LA) = (-7)(1 - p) + 8p

E(B) = 3(1 - p) + (-2)p

Player I's goal is to maximize their expected payoff, so we want to find the value of p that maximizes E(B).

Setting E(LA) = E(B) and solving for p:

(-7)(1 - p) + 8p = 3(1 - p) + (-2)p

Simplifying the equation:

-7 + 7p + 8p = 3 - 3p - 2p

15p = -4

p = -4/15 ≈ -0.267

Since probabilities must be non-negative, we conclude that Player I should assign a probability of approximately 0.267 to playing Row B.

Therefore, Player I should play Row B approximately 26.7% of the time.

To prove that if Xn → X, then f(Xn) → f(X) as n approaches infinity, we need to show that for any given ϵ > 0, there exists a positive integer N such that for all n > N, |f(Xn) - f(X)| < ϵ.

Since f is a continuous function, it is continuous at X. This means that for any ϵ > 0, there exists a δ > 0 such that |x - X| < δ implies |f(x) - f(X)| < ϵ.

In order to find the polynomial that represents the length of a rectangle with a given area of [tex]0.2x^3-0.08x^2 +0.49x+0.05[/tex] square units, we must first understand the formula for the area of a rectangle, which is length × width. We are given the area of the rectangle in terms of a polynomial expression, and we need to find the length of the rectangle, which can be represented by a polynomial expression as well.

Let's denote the length of the rectangle as 'L' and its width as 'W'. The area of the rectangle can then be represented as L × W = [tex]0.2x^3 - 0.08x^2 + 0.49x + 0.05[/tex].

We know that L = Area/W, so we can substitute in the given area to get:

To find a positive angle that is coterminal to -100°, we can add multiples of 360° to -100° until we obtain a positive angle less than 360°.

First, let's find a positive coterminal angle:

-100° + 360° = 260°

Therefore, a positive angle less than 360° that is coterminal to -100° is 260°.

Now, let's find a negative coterminal angle:

-100° - 360° = -460°

Therefore, a negative angle that is coterminal to -100° is -460°.

Here are the results:

To find coterminal angles, we add or subtract multiples of 360° from the given angle until we reach an angle in the desired range.

In this case, we added 360° to obtain a positive angle less than 360° and subtracted 360° to obtain a negative angle.

An average of 174 minutes per day with a standard deviation of 18 minutes, while Class-10 students spent an average of 118 minutes with a standard deviation of 45 minutes.

To compare the means of two independent samples, a hypothesis test can be performed using either the Z-test or t-test, depending on the sample size and whether the population standard deviations are known. In this case, the sample sizes are both 15, which is relatively small. Since the population standard deviations are unknown, the appropriate test to use is the two-sample t-test.

The null hypothesis (H0) states that the mean time spent by Class-9 students is equal to the mean time spent by Class-10 students. The alternative hypothesis (Ha) states that the means are different. By conducting the two-sample t-test and comparing the t-value to the critical value at a 0.01 significance level (using the appropriate degrees of freedom), we can determine whether to reject or fail to reject the null hypothesis.

If the calculated t-value falls within the rejection region (beyond the critical value), we reject the null hypothesis and conclude that the mean time spent by Class-9 students differs significantly from that of Class-10 students. On the other hand, if the calculated t-value falls within the non-rejection region, we fail to reject the null hypothesis, indicating that there is not enough evidence to conclude a significant difference between the mean times spent by the two classes.

The reliability of the system when connected in parallel can be calculated using the complement rule. The probability that the system fails (i.e., none of the components function properly) is the complement of the probability that at least one component functions properly. Therefore, the reliability of the system when connected in parallel is given by: Reliability (parallel) = 1 - (1 - p₁)(1 - p₂)...(1 - pₙ).

This formula assumes that the events of each component functioning properly or failing are mutually exclusive.

These formulas provide a way to calculate the reliability of the system based on the probabilities of individual component functioning properly.

The area of the region bounded by the curves f(x) = cos(x) +1 and g(x) = sin(x) + 1 on the interval -3π 5π 4 577] 4 is 2/3[tex]\pi[/tex].

The area between two curves can be found by evaluating the definite integral of the difference between the upper and lower curves over the given interval. In this case, the upper curve is f(x) = cos(x) + 1, and the lower curve is g(x) = sin(x) + 1.

To find the area, we calculate the definite integral of (f(x) - g(x)) over the interval [-3π/4, 5π/4]:

Area = ∫[-3π/4 to 5π/4] (f(x) - g(x)) dx

Substituting the given functions, the integral becomes:

Area = ∫[-3π/4 to 5π/4] [(cos(x) + 1) - (sin(x) + 1)] dx

Simplifying the expression, we have:

Area = ∫[-3π/4 to 5π/4] (cos(x) - sin(x)) dx

Evaluating this definite integral will give us the area of the region bounded by the curves f(x) = cos(x) + 1 and g(x) = sin(x) + 1 on the interval [-3π/4, 5π/4] is 2/3[tex]\pi[/tex].

An ellipse is a set of all points in a plane, such that the sum of the distances from two fixed points remains constant. These two fixed points are known as foci of the ellipse. The center of an ellipse is the midpoint of the major axis and the minor axis. The major axis is the longest diameter of the ellipse, and the minor axis is the shortest diameter of the ellipse.

(1) The given equation of the ellipse is[tex]4x² + 9y² - 8x + 18y - 23 = 0[/tex]

To find the center, we need to convert the given equation to the standard form, i.e., [tex]x²/a² + y²/b² = 1[/tex]

Divide both sides by[tex]-23 4x²/-23 + 9y²/-23 - 8x/-23 + 18y/-23 + 1 = 0[/tex]

Simplify [tex]4x²/(-23/4) + 9y²/(-23/9) - 8x/(-23/4) + 18y/(-23/9) + 1 = 0[/tex]

Compare with the standard form,[tex]x²/a² + y²/b² = 1[/tex]

The center of the ellipse is (h, k), where h = 8/(-23/4)

= -1.3913,

and k = -18/(-23/9)

= 1.5652.

Therefore, the center of the ellipse is (-1.3913, 1.5652).

(2) To find the equation of the major axis, we need to compare the lengths of a and b. a² = -23/4,

[tex]a = ±(23/4)i[/tex]

b² = -23/9,

[tex]b = ±(23/3)i[/tex]

Since a > b, the major axis is parallel to the x-axis, and its equation is y = k. Therefore, the equation of the major axis is y = 1.5652. Similarly, the equation of the minor axis is x = h.

(3) The vertices of the ellipse lie on the major axis. The distance between the center and the vertices is equal to a. The distance between the center and the major axis is b. Therefore, the distance between the center and the vertices is given by c² = a² - b² c²

= (-23/4) - (-23/9) c

[tex]= ±(23/36)i[/tex]

The vertices are given by (h ± c, k) Therefore, the vertices are [tex](-1.3913 + (23/36)i, 1.5652) and (-1.3913 - (23/36)i, 1.5652).[/tex]

(4) The co-vertices of the ellipse lie on the minor axis. The distance between the center and the co-vertices is equal to b. The distance between the center and the major axis is a. Therefore, the distance between the center and the co-vertices is given by d² = b² - a² d²

[tex]= (-23/9) - (-23/4) d[/tex]

[tex]= ±(5/6)i[/tex]

The co-vertices are given by (h, k ± d)

Therefore, the co-vertices are[tex](-1.3913, 1.5652 + (5/6)i)[/tex] and [tex](-1.3913, 1.5652 - (5/6)i).[/tex]

(5) To find the foci of the ellipse, we need to use the formula c² = a² - b² The distance between the center and the foci is equal to c. [tex]c² = (-23/4) - (-23/9) c = ±(23/36)i[/tex]

The foci are given by (h ± ci, k)

Therefore, the foci are[tex](-1.3913 + (23/36)i, 1.5652)[/tex] and[tex](-1.3913 - (23/36)i, 1.5652).[/tex]

Finally, we can sketch the ellipse with the center (-1.3913, 1.5652), major axis y = 1.5652, and minor axis x = -1.3913. We can use the vertices and co-vertices to get an approximate shape of the ellipse.

The system of linear equations has only one solution. Therefore, the value of t that satisfies the condition is:

t = (6x + 14) / 7, where x is any real number.

Since, the method of Gaussian elimination, we need to transform the system of linear equations into an equivalent system that is easier to solve.

We can do this by performing elementary row operations on the augmented matrix of the system.

The augmented matrix of the system is:

[ 3 -t | 8 ] [ 6 -2 | 2 ]

We can start by subtracting 2 times the first row from the second row to eliminate the coefficient of y in the second equation:

[ 3 -t | 8 ] [ 0 2t-2 | -14 ]

Now, if t = 1, then the coefficient of y in the second equation becomes zero. However, in this case, the system has no solution because the second equation reduces to 0 = -14, which is a contradiction.

If t ≠ 1, then we can divide the second row by 2t-2 to obtain:

[ 3 -t | 8 ] [ 0 1 | (-14) / (2t-2) ]

Now, we can use back-substitution to solve for x and y. From the second row, we have:

y = (-14) / (2t-2)

Substituting this into the first equation, we get:

3x - t(-14 / (2t-2)) = 8

Simplifying this equation, we get:

3x + 7 = t(14 / (2t-2))

Multiplying both sides by (2t-2), we get:

3x(2t-2) + 7(2t-2) = 14t

Expanding and simplifying, we get:

(6x - 7t + 14)t = 14t

Now, since the system has only one solution, this means that the two equations are not linearly dependent.

Hence, the coefficient of t in the above equation must be zero.

Therefore, we have:

6x - 7t + 14 = 0

Solving for t, we get:

t = (6x + 14) / 7

Substituting this value of t back into the system, we get:

3x - [(6x + 14) / 7] y = 8 6x - 2y = 2

Simplifying the first equation, we get:

21x - 6x - 14y = 56

Simplifying further, we get:

15x - 7y = 28

Hence, The system of linear equations has only one solution. Therefore, the value of t that satisfies the condition is:

t = (6x + 14) / 7, where x is any real number.

The function g(x) = (x² - 1)/2 satisfies f o g = h.

The given problem asks us to find a function g such that the composition of f and g, denoted as f o g, is equal to the function h. The function f(x) = 2x + 5 and h(x) = 2x² + 2x + 3 are given. To find g(x), we substitute f(x) into h(x) and solve for g(x).

By substituting f(x) into h(x), we have:

h(x) = f(g(x)) = 2(g(x)) + 5

Substituting h(x) = 2x² + 2x + 3, we get:

2x² + 2x + 3 = 2(g(x)) + 5

Rearranging the equation, we have:

2(g(x)) = 2x² + 2x - 2

Dividing both sides by 2, we get:

g(x) = (x² - 1)/2

Therefore, the function g(x) = (x² - 1)/2 satisfies f o g = h.

The composition of functions involves applying one function to the output of another function. In this problem, we are given the functions f(x) = 2x + 5 and h(x) = 2x² + 2x + 3 and are asked to find the function g(x) such that f o g = h.

option C is the correct answer.

Elaboration:

Let us consider the given integral below:∫ xdx / √9x⁴-4

Therefore,

Analysis of Variance (ANOVA) is a statistical technique used to compare the means of two or more groups or treatments.

It decomposes the total variation in the data into components attributed to different sources, allowing for the assessment of the significance of the treatment effects. In one-way ANOVA, which involves one categorical independent variable, two important components are the Sum of Squares between treatments (SSB) and the Sum of Squares within treatments (SSW).

(a) The Sum of Squares between treatments (SSB) in one-way ANOVA represents the variation in the data that can be attributed to the differences between the treatment groups. It measures the variability among the group means. SSB is obtained by summing the squared differences between each treatment mean and the overall mean, weighted by the number of observations in each treatment group. A larger SSB indicates a greater difference between the treatment means, suggesting a stronger treatment effect.

(b) The Sum of Squares within treatments (SSW) in one-way ANOVA represents the variation in the data that cannot be attributed to the treatment effects. It measures the variability within each treatment group. SSW is calculated by summing the squared differences between each individual observation and its corresponding treatment mean, across all treatment groups. SSW reflects the random variation or error within the groups. A smaller SSW indicates less variability within the groups, suggesting a more homogeneous distribution of data within each treatment.

The angles between 0 and 2π satisfying the condition cos θ = √3 / 2 are π/6 and 11π/6. For the curve y = 19 cos(5πx + 9), the amplitude is 19, the period is 2π/5, and the phase shift is π/5 to the left.

To find the angles between 0 and 2π satisfying the condition cos θ = √3 / 2, we can refer to the unit circle. At angles π/6 and 11π/6, the cosine value is √3 / 2.

For the curve y = 19 cos(5πx + 9), we can identify the properties of the cosine function. The amplitude is the absolute value of the coefficient in front of the cosine function, which in this case is 19. The period can be determined by dividing 2π by the coefficient of x, giving us a period of 2π/5. The phase shift is calculated by setting the argument of the cosine function equal to 0 and solving for x. In this case, 5πx + 9 = 0, and solving for x gives us a phase shift of -π/5, indicating a shift to the left.

ln (n + 1) - ln n = ln ((n + 1)/n)= ln (n/n + 1/n)= ln (1 + 1/n)

Now, we have to prove 1/ (n+1) < ln (1 + 1/n)

We can use the Taylor series expansion of ln (1 + x) given as ln (1 + x) = x - (x2/2) + (x3/3) - (x4/4) +...where -1 < x ≤ 1Here, x = (1/n).

Thus, we get ln (1 + 1/n) = (1/n) - (1/(2n2)) + (1/(3n3)) - (1/(4n4)) +...Now, we will remove all the positive terms and keep the negative terms.

So, we get ln (1 + 1/n) > -(1/(2n2))This means, ln (1 + 1/n) > -1/ (2n2)Now, we know that 1/ (n+1) < 1/ n.

Here, we have to prove 1/ (n+1) < ln (n + 1) - ln nThus, we can say 1/ n < ln (n + 1) - ln  So, we can write 1/ (n+1) < ln (n + 1) - ln n < ln (1 + 1/n) > -1/ (2n2)This proves that 1/ (n+1) < ln (n + 1) - ln n < n (1/n)Part (b) :

The given sequence is an = (1+ 1/2 + 1/3 +... + 1/n) - In nLet us take the difference between successive terms in the sequence. Thus, we geta(n+1) - an= [(1 + 1/2 + 1/3 +...+ 1/n + 1/(n+1)) - ln(n+1)] - [(1 + 1/2 + 1/3 +...+ 1/n) - ln n]= 1/(n+1) + ln (n/n+1)As we know that 1/ (n+1) > 0, thus the sign of an+1 - an is same as ln (n/n+1).Now, n > 0 so n + 1 > 1. This means that n/(n + 1) < 1. Therefore, ln (n/n + 1) < 0.We know that 1/ (n+1) > 0. Thus, an+1 - an < 0. This proves that {an} is decreasing for all n.Next, we have to prove that an ≥ 0 for all n.We can write an as a sum of positive terms an = 1 + (1/2 - ln 2) + (1/3 - ln 3) +...+ (1/n - ln n)As we know that ln n < 1 for all n > 1Therefore, an = 1 + (1/2 - ln 2) + (1/3 - ln 3) +...+ (1/n - ln n) > 0 + 0 + 0 +...+ 0 = 0Thus, we get an ≥ 0 for all n.Now, let us prove that {an} is convergent.The given sequence {an} is decreasing and bounded below by 0.

a. The probability that a randomly chosen light bulb lasts more than 9,400 hours is approximately 65.54%.

b. The conditions needed to use the sampling distribution of a mean are: random sampling, independence of samples, a sufficiently large sample size (such as 40 bulbs), and the skewness of the population distribution not significantly affecting the shape of the sampling distribution when the sample size is large.

c. When considering a heavily skewed population distribution, the sampling distribution of the mean will still be approximately normal due to the Central Limit Theorem..

a. Probability of a randomly chosen light bulb lasting more than 9,400 hours:

To calculate the probability that a randomly chosen light bulb lasts more than 9,400 hours, we need to find the area under the curve to the right of 9,400. This represents the probability of observing a value greater than 9,400 in a random sample.

Using the properties of the normal distribution, we can convert the value of 9,400 into a standardized z-score. The z-score measures the number of standard deviations a particular value is from the mean. In this case, we calculate the z-score using the formula:

z = (x - μ) / σ

where x is the value we are interested in (9,400), μ is the mean (9,000), and σ is the standard deviation (1,000).

z = (9,400 - 9,000) / 1,000 = 0.4

Next, we can use a standard normal distribution table or a calculator to find the probability associated with this z-score. The probability is the area under the curve to the right of the z-score.

Using a standard normal distribution table, we find that the probability associated with a z-score of 0.4 is approximately 0.6554. Therefore, the probability that a randomly chosen light bulb lasts more than 9,400 hours is approximately 0.6554, or 65.54%.

b. Conditions for using the sampling distribution of a mean:

Random Sampling: The sample of 40 bulbs should be selected randomly from the population. Each bulb in the population should have an equal chance of being included in the sample.

Independence: The bulbs in the sample should be independent of each other. This means that the lifespan of one bulb should not influence the lifespan of another.

Sample Size: The sample size should be large enough. While there is no strict rule, a sample size of 40 is generally considered sufficient for the sampling distribution of the mean to be approximately normal, regardless of the shape of the population distribution.

Skewness: The skewness of the population distribution does not significantly affect the shape of the sampling distribution of the mean when the sample size is sufficiently large. This condition implies that even if the population distribution is skewed, the sampling distribution of the mean will be close to normal if the sample size is large enough.

c. Probability of the mean lifespan of 40 randomly chosen light bulbs being more than 9,400 hours:

In this scenario, we have 40 randomly chosen light bulbs, and we want to calculate the probability that their mean lifespan is more than 9,400 hours.

To find the probability that the mean lifespan of the 40 randomly chosen light bulbs is more than 9,400 hours, we need to calculate the z-score using the formula mentioned earlier. Once we have the z-score, we can use a standard normal distribution table or a calculator to find the associated probability.

By applying the same steps as in part (a), we can determine the probability. However, it's important to note that since the distribution is heavily skewed, the mean lifespan probability may be affected by the shape of the distribution. The skewed distribution may cause the probability to deviate from the values obtained in a normal distribution scenario.
