In a random sample of ten cell​ phones, the mean full retail price was ​$450.50 and the standard deviation was ​$206.00. Assume the population is normally distributed and use the​ t-distribution to find the margin of error and construct a 95​% confidence interval for the population mean mu. Interpret the results. Identify the margin of error. nothing ▼ ​(Round to one decimal place as​ needed.)

Answers

To find the margin of error for a 95% confidence interval using the t-distribution, we first need to calculate the t-score with degrees of freedom (df) equal to the sample size minus 1 (n-1).

In this case, df = 9. Using a t-table or calculator, the t-score for a 95% confidence level and df = 9 is approximately 2.262. The margin of error can be calculated by multiplying the t-score by the standard error of the mean, which is equal to the standard deviation divided by the square root of the sample size.

In this case, the standard error of the mean is 206 / sqrt(10) = 65.20. Multiplying by the t-score, we get a margin of error of 2.262 * 65.20 = 147.54. To construct the 95% confidence interval, we can use the formula:
sample mean +/- (t-score * standard error of the mean)



Substituting in the values, we get:
$450.50 +/- (2.262 * $65.20) = $450.50 +/- $147.54

So, the 95% confidence interval for the population mean mu is $302.96 to $598.04.

Interpreting the results, we can say with 95% confidence that the true population mean full retail price of cell phones is between $302.96 and $598.04. The margin of error is the amount by which the sample mean may differ from the true population mean, and in this case it is +/- $147.54.


The 95% confidence interval for the population mean (µ) is ($304.1, $596.9), and the margin of error is $146.4. This means we can be 95% confident that the true population mean price of cell phones is between $304.1 and $596.9.

Un triangulo con 2 lineas que sus 3 angulos midan 90 grados

(se hacia con otro tipo de geometria)

Answers

The measures of the angles in the triangle are 30 degrees, 60 degrees, and 90 degrees.

In this case, we are given that the angles of the triangle are in the ratio of 1:2:3. This means that the three angles can be expressed as x, 2x, and 3x, where x is some constant factor.

To find the value of x, we need to use the fact that the sum of the angles in a triangle is 180 degrees. So, we can write an equation:

x + 2x + 3x = 180

Simplifying the equation, we get:

6x = 180

Dividing both sides by 6, we get:

x = 30

Now that we know the value of x, we can use that to find the measure of each angle in the triangle.

The first angle is x, which we know is 30 degrees.

The second angle is 2x, which is 2 times 30, or 60 degrees.

The third angle is 3x, which is 3 times 30, or 90 degrees.

b. The median is more resistant, which indicates that it usually changes less than the mean when comparing data with and without outliers. A.

Outliers are data points that are significantly different from the other values in a data set.

These observations can be identified by looking at a histogram, where they are separated from the main group of data by a significant space.

Outliers can be mistakes or they may represent real but unusual values.

It is important to look at outliers in closer context to determine how to treat them.

Sometimes they may be included in the analysis, but other times they may be removed or corrected.
To determine which measure of center, mean or median, is more resistant to outliers, we need to understand what "resistant to outliers" means.

Resistance to outliers refers to how much a measure of center is affected by the presence of outliers.

A measure that is more resistant to outliers will change less when outliers are present.
The median is more resistant to outliers than the mean.

This means that the median usually changes less than the mean when comparing data with and without outliers.

The reason for this is that the median is calculated by taking the middle value of the data set, which is less affected by extreme values than the mean, which takes into account all values in the data set.
Outliers should be examined carefully in the context of the data set to determine how to treat them.

The median is more resistant to outliers than the mean, which makes it a better measure of center when outliers are present.

Suppose a graduate student is studying a population of bluebonnets along a roadside. The plants in this population are genetically variable. She counts the seeds produced by 100 plants and measures the mean and variance of seed number. The variance is 25. Selecting one plant, the student takes cuttings from it and cultivates them, producing many genetically identical clones. She then transplants these clones into the roadside population, allows them to grow for one year, and then counts the number of seeds produced. Thestudent finds that the variance in seed number among the cloned plants is 10. From the phenotypic variance (p) of the genetically variable and genetically identical plants, calculate thebroad-sense heritability (H) of seed number for the roadside population of bluebonnets

Answers

From the phenotypic variance (p) of the genetically variable and genetically identical plants, the value of the broad-sense heritability (H) of seed number for the roadside population of bluebonnets is equals to the 0.6.

We have, population of graduation studying students in bluebonnets along a roadside. Sample size of plants = 100

variance for plants = 25

=> standard deviations = 5

We have to determine the broad-sense heritability (H) of seed number for the roadside. Broad-sense heritability [tex]H2 = \frac{V_G }{ V_P} [/tex] ---(1)

The phenotypic variation [tex]V_P = V_G + V_E [/tex], here [tex] V_P = 25[/tex]

[tex]25 = V_G + V_E[/tex] ------(II)

In the identical population, [tex] V_G = 0[/tex] and here [tex] V_P = 10[/tex]

=> [tex]10 = 0 + V_E [/tex]

=> [tex]V_E= 10[/tex]

By substituting [tex]V_E[/tex] value in equation (II), we will determine [tex]25 = V_G + 10 [/tex]

=> [tex]V_G = 15[/tex]

Substitute the values of [tex]V_G and V_E [/tex] of the roadside population in equation (1), [tex]H²=\frac{15}{25}=0.6[/tex].

The key to the answer is assumption should be the genetic variance of the genetically identical plants is the same as the genetically variable population.

a poster must have an area of with 1-inch margins at the bottom and sides of the poster and a 2-inch margin at the top. what dimensions will give the largest printed area?

Answers

So, the dimensions that give the largest printed area are 6.5 inches by 8 inches, with 1-inch margins at the bottom and sides, and a 2-inch margin at the top.

Let the dimensions of the printed area be x and y. Then we have:

The bottom margin is 1 inch, so the height of the poster is y + 2 + 1 = y + 3 inches.

The side margins are 1 inch each, so the width of the poster is x + 2 inches.

The top margin is 2 inches, so the height of the printed area is y.

Therefore, the total area of the poster is:

A = (y + 3) * (x + 2)

Expanding this expression, we get:

A = xy + 3x + 2y + 6

To maximize the printed area, we need to find the values of x and y that maximize A. To do this, we can use calculus. We differentiate A with respect to x and y, and set the derivatives equal to zero to find the critical points:

dA/dx = y + 3 = 0

dA/dy = x + 2 = 0

Solving these equations simultaneously, we get:

y = -3

x = -2

These values are not physically meaningful, since x and y represent dimensions of a poster and cannot be negative. However, they tell us that A has no local maxima or minima. Therefore, to maximize A, we need to consider the endpoints of the feasible region, which are determined by the margins.

The feasible region is a rectangle with height y = 11 - 2 - 1 = 8 inches and width x = 8.5 - 2 = 6.5 inches. Therefore, the maximum area is:

A = (8 * 6.5) - (3 * 2)

Answers

The F statistic for this data set is 1.93, with a p-value of 0.098. This means that we cannot reject the null hypothesis that there is no difference between the means of the cities at a significance level of 0.05.

Therefore, we cannot conclude that there is a significant difference in hotel costs per night between the five cities.

To find the value of the test statistic to test for a difference between cities, we need to perform a statistical test such as a one-way ANOVA (analysis of variance) test. This test compares the variation between the means of multiple groups to the variation within each group. The test statistic for a one-way ANOVA is F.

To calculate the F statistic, we need to first find the sum of squares within groups (SSW) and the sum of squares between groups (SSB). SSW measures the variation within each group and SSB measures the variation between groups.

SSW = ∑(xi – xj)² / df_within

where xi is the value of each observation, xj is the mean of each group, and df_within is the degrees of freedom within groups, which is equal to the total number of observations minus the number of groups.

SSB = ∑(xj – xbar)² / df_between

where xbar is the grand mean of all the observations, and df_between is the degrees of freedom between groups, which is equal to the number of groups minus one.

Once we have calculated SSW and SSB, we can calculate the F statistic as:

F = SSB / df_between / (SSW / df_within)

If the F statistic is greater than the critical value from the F distribution table, we can reject the null hypothesis that there is no difference between the means of the groups.

In this case, we have five cities: New York, Los Angeles, Atlanta, Houston, and Phoenix. We can use Excel or another statistical software to calculate the ANOVA test.

The F statistic of 1.93 and the associated p-value of 0.098 indicate that we cannot reject the null hypothesis at a significance level of 0.05. This suggests that there is no significant difference in hotel costs per night among the five cities: New York, Los Angeles, Atlanta, Houston, and Phoenix. The analysis was performed using a one-way ANOVA test, comparing the variation between the means of the cities to the variation within each city.

What is fraction?

A fraction is a mathematical term that represents a part of a whole or a ratio between two quantities. It is a way of expressing a number as a quotient of two integers, where the top number is called the numerator, and the bottom number is called the denominator.

By the multiplicative property of the Legendre symbol, we know that $(\frac{-2}{p}) = (\frac{-1}{p}) (\frac{2}{p})$.

We have $(\frac{-1}{p})=(-1)^{\frac{p-1}{2}}$. Therefore, $(\frac{-1}{p})=1$ if $p\equiv 1\pmod{4}$, and $(\frac{-1}{p})=-1$ if $p\equiv 3\pmod{4}$.

To evaluate $(\frac{2}{p})$, we use the quadratic reciprocity law. We have $(\frac{2}{p})=(-1)^{\frac{p^2-1}{8}}(\frac{p}{2})$, where $(\frac{p}{2})$ is the Legendre symbol.

We have $(\frac{p}{2})=1$ if $p\equiv \pm 1\pmod{8}$ and $(\frac{p}{2})=-1$ if $p\equiv \pm 3\pmod{8}$.

Therefore, $(\frac{2}{p})=(-1)^{\frac{p^2-1}{8}}(\frac{p}{2})$ is equal to $1$ if $p\equiv \pm 1\pmod{8}$ and $-1$ if $p\equiv \pm 3\pmod{8}$.

Putting it all together, we have $(\frac{-2}{p}) = (\frac{-1}{p}) (\frac{2}{p}) = 1$ if $p\equiv 1\pmod{4}$ and $p\equiv \pm 1\pmod{8}$, and $(\frac{-2}{p}) = (\frac{-1}{p}) (\frac{2}{p}) = -1$ if $p\equiv 3\pmod{4}$ and $p\equiv \pm 3\pmod{8}$.

Therefore, we can conclude that $(\frac{-2}{p})=1$ if and only if $p\equiv \pm 1\pmod{8}$, and $(\frac{-2}{p})=-1$ if and only if $p\equiv \pm 3\pmod{8}$.

western lowland gorillas, whose main habitat is the central african continent, have a mean weight of 275 pounds with a standard deviation of 40 pounds. capuchin monkeys, whose main habitat is brazil and a few other parts of latin america, have a mean weight of 6 pounds with a standard deviation of 1.1 pounds. both weight distributions are approximately normally distributed. if a particular western lowland gorilla is known to weigh 345 pounds, approximately how much would a capuchin monkey have to weigh, in pounds, to have the same standardized weight as the lowland gorilla?

Answers

To find the capuchin monkey's weight with the same standardized weight as the lowland gorilla, we need to first calculate the z-score of the gorilla's weight.

The z-score represents how many standard deviations a data point is away from the mean.

For the gorilla with a weight of 345 pounds, the z-score can be calculated as follows: Z-score = (Weight - Mean) / Standard Deviation
Z-score = (345 - 275) / 40 = 70 / 40 = 1.75.

So a gorilla weighing 345 pounds has a standardized weight of 1.75 standard deviations above the mean. Now we need to find out how much a capuchin monkey would have to weigh to have the same standardized weight.

We can use the same formula and solve for x: z = (x - mean) / standard deviation .


1.75 = (x - 6) / 1.1
1.925 = x - 6
x = 7.925



So a capuchin monkey would have to weigh approximately 7.925 pounds to have the same standardized weight as a gorilla weighing 345 pounds. It's important to note that standardized weights are not the same as actual weights.

They are simply a way to compare values from different distributions on a common scale.

Now that we have the z-score, we can use it to find the capuchin monkey's weight with the same standardized weight: Weight = Mean + (Z-score × Standard Deviation), Weight = 6 + (1.75 × 1.1) = 6 + 1.925 = 7.925.


Therefore, a capuchin monkey would have to weigh approximately 7.93 pounds to have the same standardized weight as the lowland gorilla.

No. It is not true that if B is produced by interchanging two rows of A, then detB = detA.

det(B) = -det(A) is the correct formula for calculating the determinant of a matrix obtained by interchanging two rows of another matrix.

Two rows of a matrix are interchanged, the determinant of the resulting matrix is equal to the determinant of the original matrix multiplied by -1.

Therefore, we have det(B) = -det(A).

This can be seen from the formula for calculating the determinant of a matrix.

When two rows are interchanged, the determinant of the resulting matrix is equal to the determinant of the original matrix multiplied by -1 raised to the power of the number of row interchanges.

Since we have interchanged two rows, the power is 2, so the determinant of the resulting matrix is equal to the determinant of the original matrix multiplied by (-1)² = 1.

the probability of obtaining between 55 and 69 tails, inclusive, is approximately 0.7171.

To use the normal distribution to approximate a binomial distribution, we need to use the following formula for the mean and standard deviation:

mean = n * p

standard deviation = sqrt(n * p * (1 - p))

where n is the number of trials, p is the probability of success for each trial.

In this case, n = 130 and p = 0.5 since the coin is fair. So we have:

mean = 130 * 0.5 = 65

standard deviation = sqrt(130 * 0.5 * (1 - 0.5)) = 5.6969 (rounded to four decimal places)

Now we can use the normal distribution to approximate the binomial distribution:

P(55 <= X <= 69) = P(Z <= (69 - 65) / 5.6969) - P(Z <= (55 - 65) / 5.6969)

where Z is a standard normal random variable

P(Z <= 0.7021) - P(Z <= -1.7546) = 0.7579 - 0.0408 = 0.7171 (rounded to four decimal places)

What is the law of cosines?

The Law of Cosines is a trigonometric formula that relates the lengths of the sides of a triangle to the cosine of one of its angles.

The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite to side c, the following equation holds true:

c^2 = a^2 + b^2 - 2ab cos(C)

The parameters for this problem are given as follows:

a = 5, b = 6 and C = 60º.

Hence the length C is obtained as follows:

c² = 5² + 6² - 2 x 5 x 6 x cosine of 60 degrees

c² = 31.

X = number of cities in which it will rain tomorrow among five neighboring cities located within 10 miles of each other.

Answers

Given the problem, X represents the number of cities among the five neighboring cities (located within 10 miles of each other) in which it will rain tomorrow. X can be a value ranging from 0 (no rain in any city) to 5 (rain in all cities).

Based on the given information, X is the random variable representing the number of cities among the five neighboring cities that will experience rain tomorrow. Since the cities are located within 10 miles of each other, it can be assumed that they are geographically similar and therefore have similar weather patterns. However, the probability of rain occurring in each city may still vary due to microclimates or other factors.

In order to determine the probability distribution of X, more information is needed such as historical weather data, current weather conditions, and any forecasts or predictions. Without this additional information, it is not possible to provide a specific answer to the question.

Compute the hypergeometric probabilities for the following values of n and x. Assume N = 8 and r = 4. (Round your answers to four decimal places.
(a) n = 4, x = 2
(b) n = 6, x = 3
(c) n = 3. x = 0
(d) n = 3, x = 3

Answers

The hypergeometric probabilities for the given values of n and x are:

(a) P(X = 2) = 0.5143

(b) P(X = 3) = 0.1429

(c) P(X = 0) = 0.3571

(d) P(X = 3) = 0.0714

The hypergeometric probability mass function is given by:

P(X = x) = (rCx)(N-rCn-x) / (NCn)

where N is the total number of items in the population, r is the number of "successes" in the population, n is the sample size, and x is the number of "successes" in the sample.

(a) For n = 4 and x = 2:

P(X = 2) = (4C2)(8-4C4-2) / (8C4)

= (6)(6) / (70)

= 0.5143

(b) For n = 6 and x = 3:

P(X = 3) = (4C3)(8-4C6-3) / (8C6)

= (4)(1) / (28)

= 0.1429

(c) For n = 3 and x = 0:

P(X = 0) = (4C0)(8-4C3-0) / (8C3)

= (1)(20) / (56)

= 0.3571

(d) For n = 3 and x = 3:

P(X = 3) = (4C3)(8-4C3-3) / (8C3)

= (4)(1) / (56)

= 0.0714

Therefore, the hypergeometric probabilities for the given values of n and x are:

(a) P(X = 2) = 0.5143

(b) P(X = 3) = 0.1429

(c) P(X = 0) = 0.3571

(d) P(X = 3) = 0.0714
