just before a presidential election, a national opinion poll increases the size of its weekly sample from the usual 1500 people to 4000 people. (a) Does the larger random sample reduce the bias of the poll result? Explain. (b) Does it reduce the variability of the result? Explain.

Answers

The larger random sample of 4000 people can reduce the bias and variability of the poll result by increasing the chances that the sample reflects the population accurately, reducing the effect of chance on the sample drawn, and increasing the precision of the estimate.

(a) Yes, the larger random sample can reduce the bias of the poll result. A larger sample size increases the chances that the sample accurately reflects the population by reducing the effect of chance on the sample drawn. This in turn reduces the likelihood of sampling bias, which occurs when a sample is unrepresentative of the population being studied.

(b) Yes, the larger random sample can reduce the variability of the result. A larger sample size increases the chances that the sample accurately reflects the population, which reduces the variability of the results. A larger sample size also increases the precision of the estimate, which reduces the variability of the results.

sum of the digits of a 2 digit number is 8.when the digits of the number are interchanged the resulting new number is smaller than the original number by 36. what is the original number.​

Answers

Answer:

The original number is 62.

Step-by-step explanation:

Solution :

Let,

Units digit = x

Tens digit = 8 - x

★ Original number :

10 (8 - x) + x

80 - 10x + x

80 - 9x

When the digits of the number are interchanged :

10 (x) + 8 - x

10 x + 8 - x

9x + 8

(80 - 9x) - 36 = 9x + 8

80 - 36 - 9x = 9x + 8

44 - 9x = 9x + 8

44 - 8 = 9x + 9x

36 = 18x

x = 36/18

x = 2

Units digit = 2

Tens digit = 8 - x

8 - 2 = 6

Therefore, the original number is 62.

We want to know how many people plan on buying a new car this year. Determine the sample size needed for a one proportion confidence interval to estimate this with a margin of error of 0.06 and a 95% confidence interval. We don't have any idea what the population proportion would be.

Answers

The required sample size for the confidence interval is given as follows:

n = 267.

What is a confidence interval of proportions?

A confidence interval of proportions has the bounds given by the rule presented as follows:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the variables used to calculated these bounds are listed as follows:

[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.

The margin of error is defined as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The parameters for this problem are given as follows:

[tex]M = 0.06, \pi = 0.5[/tex]

The estimate is of 0.5 as it is when the highest sample size is needed, and the sample size is obtained as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.06 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]

[tex]0.06\sqrt{n} = 1.96 \times 0.5[/tex]

[tex]\sqrt{n} = \frac{1.96 \times 0.5}{0.06}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.96 \times 0.5}{0.06}\right)[/tex]

1. Draw a box plot for quiz scores of her class.
2. What are the highest and the lowest quiz score?
3. What is the score that separates the bottom 75% from the top 25%?
4. How many students scored more than the median?
5. How many students scored more than 14 points?
6. What percent of her students received less than 12 points?
7. Would the score of 4 be an outlier? (use the IQR method to explain)

Answers

To draw a box plot for the quiz scores of Professor A's class, you would start by drawing a number line along the horizontal axis and marking the minimum, Q1, median, Q3, and maximum scores.

Then, you would draw a box from Q1 to Q3 to represent the middle 50% of the data in professor A's class. The median score would be marked within the box, and a line would be drawn from either end of the box to the minimum and maximum scores to represent the lower and upper extremes of the data.

The highest quiz score is 20, and the lowest quiz score is 3.

The score that separates the bottom 75% from the top 25% is Q3, which is 16.

By definition, half of the class should have scored more than the median, so 20 students scored more than 14 points.

By definition, the median is 14, so half of the class should have scored more than 14 points, so 20 students scored more than 14 points.

Using the min value and Q1 value, we know that 25% of the students scored less than 12 points.

To determine if 4 is an outlier, we can use the IQR (interquartile range) method, which is calculated by subtracting Q1 from Q3. In this case, the IQR is 4 (16 minus 12). We can then use the IQR to find the lower and upper bounds of the data, which are determined by subtracting 1.5 IQR from Q1 and adding 1.5 IQR to Q3. In this case, the lower bound is 8 (12 minus 1.54) and the upper bound is 20 (16 plus 1.54). 4 is lower than the lower bound; therefore, it is considered an outlier.

Question 1 Integrate each of the following:
(a) x² - 2x + 1/x²
(b) x(x + 3)²​

Answers

Step-by-step explanation:

I've skipped some steps. Hope you get this.

Answer:

(a) [tex]\displaystyle{\int \left(x^2-2x+\dfrac{1}{x^2}\right) \, dx} = \dfrac{x^3}{3} - x^2 - \dfrac{1}{x} + \text{C}}[/tex]

(b) [tex]\displaystyle{\int x\left(x+3\right)^2 \, dx = \dfrac{x^4}{4} + 2x^3 + \dfrac{9x^2}{2} + \text{C}}[/tex]

Step-by-step explanation:

Part A

Consider the indefinite integral with respect to x:

[tex]\displaystyle{\int \left(x^2-2x+\dfrac{1}{x^2}\right) \, dx}[/tex]

We can separately integrate each terms as they are in addition and subtraction:

[tex]\displaystyle{\int x^2 \, dx - \int 2x \, dx + \int \dfrac{1}{x^2} \, dx}[/tex]

For the last term, we can rewrite in negative exponent as [tex]x^{-2}[/tex] so we can apply power rules to all these terms (making it easier):

[tex]\displaystyle{\int x^2 \, dx - \int 2x \, dx + \int x^{-2} \, dx}[/tex]

The middle term -- we can separate the constant out of integral:

[tex]\displaystyle{\int x^2 \, dx - 2\int x \, dx + \int x^{-2} \, dx}[/tex]

Apply the power integration rule (for n ≠ 1):
[tex]\displaystyle{\int x^n \, dx = \dfrac{x^{n+1}}{n+1} + \text{C} \ \ \left(\text{where C is a constant}\right)}[/tex]

But we can add C later after we integrate all these terms, therefore:

[tex]\displaystyle{\dfrac{x^{2+1}}{2+1} - 2\cdot \dfrac{x^{1+1}}{1+1} + \dfrac{x^{-2+1}}{-2+1}}\\\\\displaystyle{\dfrac{x^{3}}{3} - 2\cdot \dfrac{x^{2}}{2} + \dfrac{x^{-1}}{-1}}\\\\\displaystyle{\dfrac{x^3}{3} - x^2 - x^{-1}}[/tex]

Rewrite the negative exponent back to fraction form:

[tex]\displaystyle{\dfrac{x^3}{3} - x^2 - \dfrac{1}{x}}[/tex]

After integrating all terms, we add + C every time. Hence:

[tex]\displaystyle{\int \left(x^2-2x+\dfrac{1}{x^2}\right) \, dx} = \dfrac{x^3}{3} - x^2 - \dfrac{1}{x} + \text{C}}[/tex]

Part B

Consider the indefinite integration with respect to x of:

[tex]\displaystyle{\int x\left(x+3\right)^2 \, dx}[/tex]

First, expand (x + 3)² to x² + 6x + 9:

[tex]\displaystyle{\int x\left(x^2+6x+9\right) \, dx}[/tex]

Then disribute the x inside the brackets:

[tex]\displaystyle{\int \left(x^3+6x^2+9x\right) \, dx}[/tex]

Integrate separately:

[tex]\displaystyle{\int x^3 \, dx + \int 6x^2 \, dx + \int 9x \, dx}[/tex]

Separate the constants:

[tex]\displaystyle{\int x^3 \, dx + 6\int x^2 \, dx + 9\int x \, dx}[/tex]

For the power integration formula, recall above. Thus:

[tex]\displaystyle{\dfrac{x^{3+1}}{3+1} + 6 \cdot \dfrac{x^{2+1}}{2+1} + 9 \cdot \dfrac{x^{1+1}}{1+1}}\\\\\displaystyle{\dfrac{x^{4}}{4} + 6 \cdot \dfrac{x^{3}}{3} + 9 \cdot \dfrac{x^{2}}{2}}\\\\\displaystyle{\dfrac{x^4}{4} + 2x^3 + \dfrac{9x^2}{2}}[/tex]

Add + C after finishing the integration process, hence:

[tex]\displaystyle{\int x\left(x+3\right)^2 \, dx = \dfrac{x^4}{4} + 2x^3 + \dfrac{9x^2}{2} + \text{C}}[/tex]

a teacher is lecturing on excel macros. they plan to divide the class into groups of 5 and want each group to work on a unique exercise. to determine the number of exercises needed, model this situation with an equation, using x as the independent variable and y as the dependent variable.

Answers

In this situation, the independent variable is x, which is the number of groups, and the dependent variable is y, which is the number of exercises needed.

To model this situation with an equation, we need to calculate the number of exercises needed for each group. Since we have x groups, and each group needs a unique exercise, we can calculate the number of exercises needed by multiplying the number of groups by 5, since each group has 5 members. Thus, the equation would be y = 5x. This equation uses the fact that each group is made up of 5 members, so each group needs a unique exercise. In order to determine the number of exercises needed, we can solve the equation for x by dividing both sides by 5. This gives us x=y/5, which indicates that the number of exercises (x) is equal to the number of groups (y) divided by 5.For example, if we have 8 groups, then the number of exercises needed would be 5*8 = 40.In this situation, the independent variable is x, which is the number of groups, and the dependent variable is y, which is the number of exercises needed.

What is 4(-8)+8= and how can I find it

Answers

Answer: -24

Step-by-step explanation:

⇒4(-8)+8

in such questions, first solve the bracket. In this question there is only a single term within the bracket, -8. Brackets usually mean multiplication. So we multiply 8 by 4 to get 32. Now since we need to give 32 a sign as well, so in case of multiplication we multiply the sign of 8 and 4 together i.e negative and positive respectively. Negative positive multiplied give us negative. Therefore the sign of 32 will be negative.

⇒- 32 + 8

now again we are stuck with the sign issue. Notice that we have both a negative and a positive sign as well. How do we know if we are supposed to add or subtract? In order to decide which operation we apply on the two numbers, we first multiply the signs. Negative positive multiplied give negative, therfore we will do subtraction. 32 subtracted from 8 gives 24. Now again we are supposed to give 24 a sign. Unlike in multiplication, when we do addition or subtraction, instead of multiplying the signs to give the result a sign, we look for the sign of the greater operand, i.e 32, because 32 is greater than 8 and has a negative sign, so we give 24 a negative sign.

The painting crew will take approximately 38 hours to complete the 24-mile stretch of road.

What is painting crew?

Painting crew is a group of professional painters responsible for completing painting projects. They typically work on both interior and exterior painting projects and often specialize in specific types of paint finishes, such as faux finishes or specialty finishes. Painting crew members typically have a good understanding of painting techniques and tools, such as brushes and rollers, as well as a basic understanding of the chemistry involved in mixing paints.

This is calculated by taking the remaining miles (24 miles - 9.5 miles = 14.5 miles) and
dividing it by the rate at which they are painting (14.5 miles / 0.25 miles per hour = 58 hours).
Then we subtract the amount of hours they have already worked (58 hours - 9.5 hours = 38 hours).

Answers

Answer:

K) x = - 2 and x = 2

Step-by-step explanation:

Vertical asymptotes occur when the denominator of a fraction equals to zero, but the numerator does not. In the case of y = 1/x^2 - 4, the denominator is x^2 - 4.

The equation x^2 - 4 = 0 represents the points at which the denominator equals to zero, so we can find the solutions for x by solving this equation:

x^2 - 4 = 0

x^2 = 4

x = ±2

So x = 2 and x = -2 represents the vertical asymptote of the graph of y = 1/x^2 - 4

This means that the graph of the function approaches zero as x approaches 2 and -2 from the left and right respectively, but it never touches the x-axis at those points.

When a customer buys a family-sized meal at a certain restaurant, they get to choose 3 side dishes from 9 options. Suppose a customer is going to choose 3 different side dishes.
How many groups of 3 different side dishes are possible?

Answers

There amount are 504 different groups of 3 side dishes that a customer can choose from.

There are 9 possible side dishes, and the customer can choose any 3 of them. The number of different groups of 3 side dishes can be determined using the formula:

nCr = n!/(r!(n-r)!).

In this case,

n = 9 and r = 3,

so the number of possible groups is

9!/(3!(9-3)!) = 504.

When a customer buys a family-sized meal at a certain restaurant, they get to choose 3 side dishes from 9 options. The number of different groups of 3 side dishes possible for the customer to choose from can be determined using the formula for combination: nCr = n!/(r!(n-r)!). In this case, n = 9 (the number of possible side dishes) and r = 3 (the number of side dishes chosen). Applying the formula, the number of possible groups of 3 side dishes is 9!/(3!(9-3)!) = 504.

The proportion of adults for which the test would be positive isA) 0.00099B) 0.01998C) 0.02097D) 0.02100

Answers

Adults make up 0.02100 of the probability for whom the test would be positive.

The proportion of adults for which the test would be positive can be calculated by multiplying the probability of a randomly selected adult having the rare disease (0.001) by the probability that the test will be positive for a person with the disease (0.99) and adding it to the probability that the test will be positive for a person without the disease (0.02).

0.001 x 0.99 = 0.00099

0.00099 + 0.02 = 0.02099

0.02099 = 0.02100 (rounded)

Therefore, the proportion of adults for which the test would be positive is 0.02100.The proportion of adults for which the test would be positive is 0.02100, which is calculated by taking into account the probability of a randomly selected adult having the rare disease (0.001) and the probability that the test will be positive for a person with the disease (0.99) and a person without the disease (0.02). This reflects how the test is not perfect and can sometimes give false positives or false negatives. The result of 0.02100 indicates that out of every 1000 adults, 2 of them will have a positive test result.

How many dining tables should Vincent produce, and what is the total cost of his production?

Answers

The total cost of production of six dining tables is $1300.

How many tables to be produced?

Production is the act of combining a variety of material and immaterial inputs to create an output. In a perfect world, this output would be a good or valuable good or service for people to use. The three main production factors of land, labor, and capital are known as primary producers of goods or services.

These crucial inputs are not significantly altered by the output process or the end product, nor are they made a crucial component of it. In classical economics, materials and energy are regarded as secondary factors because they are byproducts of land, labor, and capital. Technology and entrepreneurship are sometimes seen as evolved variables in production in addition to the conventional components of production.

Each dining table for $1,000
