4. Which expression represents "4 less than the product of 2 and a number e"?

Suppose the null hypothesis is not rejected. State the conclusion based on the results of the test. Three years ago, the mean p

Likurg_2 [28]

Answer:

A. There is not sufficient evidence to conclude that the mean price of a single-family home has decreased

Step-by-step explanation:

To study : Whether the mean price of single family home has decreased or not -

Null Hypothesis [H0] = There is no change in mean price of single family home

Alternate Hypothesis [H1] = There is change (decrease) in mean price of single family home

If the null hypothesis is not rejected, it implies that 'there is no change in mean price of single family home' has been statistically accepted.

So, it states that - There is not sufficient evidence to conclude that the mean price of a single-family home has decreased

Volume of a Cone Formula: $\displaystyle V = \frac{1}{3} \pi r^2h$

r is radius
h is height

Step-by-step explanation:

Step 1: Define

Radius r = 4

Height h = 21

Step 2: Find Volume

Substitute in variables [Volume of a Cone Formula]: $\displaystyle V = \frac{1}{3} \pi (4)^2(21)$
Evaluate exponents: $\displaystyle V = \frac{1}{3} \pi (16)(21)$
Multiply: $\displaystyle V = \frac{16 \pi}{3}(21)$
Multiply: $\displaystyle V = 16 \pi \cdot 7$
Multiply: $\displaystyle V = 112 \pi$

Let’s assume the following statements are true: Historically, 75% of the five-star football recruits in the nation go to univers

marishachu [46]

Given:
75% of the five-star football recruits in the nation go to universities in the three most competitive athletic conferences. → 25% goes to other schools.

five-star recruits get full football scholarships 93% of the time, regardless of which conference they go to. → 7% of the 5-star recruits don't get full football scholarships.

a. The probability that a randomly selected five-star recruit who chooses one of the best three conferences will be offered a full football scholarship?
75% * 93% = 69.75%

b. What are the odds a randomly selected five-star recruit will not select a university from one of the three best conferences?
25% of selected five-star recruit will not select a university from one of the three best conferences. I got the number based on the given data. Since, 75% will go, the remaining percent won't go. Total percentage should be 100% of the population.

c. Explain whether these are independent or dependent events. Are they Inclusive or exclusive?
These are independent events. One can still go to different school and still be legible for the full football scholarship.

For question 2, pls. see attachment.
