Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.04 and a standard deviation of 1.52. Using the empirical rule, what percentage of American women have shoe sizes that are at least 12.6?

Please do not round your answer.

Answer 1

Answer:

0.15 % of American women have a shoe size greater than 12.6

Explanation:

*See the attached photo.

Suppose That Shoe Sizes Of American Women Have A Bell-shaped Distribution With A Mean Of 8.04 And A Standard
Answer 2

The percentage of American women that have shoe sizes that are at least 12.6 is; 0.0015

Empirical Rule

We are given;

Mean; x' = 8.04

Standard deviation; σ = 1.52

Using the empirical rule, we can have the data either 1, 2 or 3 standard deviations from the mean.

Thus;

At 1 standard deviation from mean, we have;

8.04 ± 1(1.52)

⇒ (6.52, 8.56)

At 2 standard deviations from the mean, we have;

8.04 ± 2(1.52)

⇒ (5, 11.08)

At 3 standard deviations from the mean, we have;

8.04 ± 3(1.52)

⇒ (3.48, 12.6)

We can see that the one with at least 12,6 is 3 standard deviations from the mean which from empirical rule is 99.7%

Thus;

percentage of American women have shoe sizes that are at least 12.6 = 100% - 99.7% - 0.15%

P(x ≥ 12.6) = 0.15% = 0.0015

g Dissmore's has reduced prices by 17% on everything to thank their customers for their patronage. If Ben & Jerry's ® Phish Food TM ice cream cost $2.99 before the price reduction, how much does it cost now? (Round your answer to the nearest penny.)

Answers

Answer:

The ice cream will cost $2.5 after the price reduction.

Explanation:

This problem represents a percent decrease

To perform a percent decrease on the ice cream, we need to take 17% of the old price, and subtract that from the old price.

Let's set up the equation. Let x = the new price.

\(2.99 - \frac{17*2.99}{100} = x\)

\(2.99 - \frac{50.83}{100} = x\)

\(2.99 - 0.5083 = x\)

\(2.5 = x\)

The ice cream will cost $2.5 after the price reduction.

Explanation:

The sample proportion based on the question that we have here is 0.72

What is sample proportion?

The sample proportion (p) indicates the percentage of people in a sample who exhibit a particular quality or attribute. Divide the number of individuals (or items) who have the desired attribute by the overall sample size to obtain the sample proportion.

P=X/N, where X represents the number of successes and N represents the sample size, yields the sample proportion.

Hence from the question, we see that 72% of the passengers booked for flights actually show up.  hence the proportion is 0.72.

The average math score for the class 5 is 23.6. A researcher is interested to check if the score is higher in class 5 that in USA. How many students are needed to ensure that a two-sided test of hypothesis has 80% power to detect a difference in score of 2 marks? If the population standard deviation is 5.7.

Answers

Answer:

To calculate the sample size needed for a study with a certain power, we need to use the formula for power in a two-sample t-test. The formula is:

n = [(Zα/2 + Zβ)^2 * 2 * σ^2] / d^2

where:

- Zα/2 is the critical value from the standard normal distribution for a two-tailed test with the desired level of confidence. If we want a 95% confidence level (typical for this kind of test), Zα/2 would be approximately 1.96.

- Zβ is the critical value corresponding to the desired power. If we want 80% power, Zβ is approximately 0.84.

- σ is the population standard deviation, which is given as 5.7.

- d is the difference we want to detect, which is 2 in this case.

Plugging these values into the formula, we get:

n = [(1.96 + 0.84)^2 * 2 * (5.7)^2] / (2)^2

Now we can calculate this:

n = [7.8 * 2 * 32.49] / 4

n = [504.72] / 4

n = 126.18

The sample size should be a whole number, and it's generally recommended to round up to ensure sufficient power, so we would need a sample size of approximately 127 students in class 5 to have 80% power to detect a difference of 2 marks.

The number of tickets purchased by an individual for Beckham College’s holiday music festival is a uniformly distributed random variable ranging from 2 to 10. Find the mean and standard deviation of this random variable. (Round your answers to 2 decimal places.)

Answers

Answer:

The mean of the distribution is 4.00 and the standard deviation is 2.31

Explanation:

Given

Range = 2 to 10

Type of distribution = uniform distribution

Required

1. Mean

2. Standard Deviation

The mean of uniform distribution is calculated as thus;

\(Mean = \frac{1}{2}(a + b)\)

Where b and a are the intervals of the distribution

b = upper bound = 10

a = lower bound = 2

So,

\(Mean = \frac{1}{2}(a + b)\)

Substitute 10 for b and 2 for a

\(Mean = \frac{1}{2}(2 + 10)\)

\(Mean = \frac{1}{2}(12)\)

\(Mean = \frac{1}{2} * 12\)

\(Mean = 6\)

\(Mean = 6.00\) (Approximated to 2 decimal places)

The standard deviation of uniform distribution is calculated as thus;

σ = √σ²

Where σ represents the standard deviation and σ² represents the variance.

Calculate variance

σ² = Var

\(Var = \frac{(b-a)^2}{12}\)

Substitute 10 for b and 2 for a

\(Var = \frac{(10 - 2)^2}{12}\)

\(Var = \frac{8^2}{12}\)

\(Var = \frac{64}{12}\)

\(Var = 5.33\)

Recall that

σ = √σ² = √Var

Substitute 5.33 for Var

σ = √5.33

σ = 2.309401076758503

σ = 2.31 (Approximated)

Hence, the mean of the distribution is 4.00 and the standard deviation is 2.31
