Answer:
Option B is correct.
Use the difference in sample means (10 and 8) in a hypothesis test for a difference in two population means.
Step-by-step Explanation:
The clear, complete table For this question is presented in the attached image to this solution.
It should be noted that For this question, the running coach wants to test if participating in weekly running clubs significantly improves the time to run a mile.
In the data setup, the mean time to run a mile in January for those that participate in weekly running clubs and those that do not was provided.
The mean time to run a mile in June too is provided for those that participate in weekly running clubs and those that do not.
Then the difference in the mean time to run a mile in January and June for the two classes (those that participate in weekly running clubs and those that do not) is also provided.
Since, the aim of the running coach is to test if participating in weekly running clubs significantly improves the time to run a mile, so, it is logical that it is the improvements in running times for the two groups that should be compared.
Hence, we should use the difference in sample means (10 and 8) in a hypothesis test for a difference in two population means.

Answer:
- <em><u>$869,776</u></em>
Explanation:
<u>1. Mortgage table</u>
Find attached a sample of a mortgage table per 1,000 dollars borrowed.
You have to use the number in the intersection of the row for 5.25% interest and the column for 20 years.
The number is $6.74.
That means that, for every $1,000 borrowed for 20 years at 5.25% interest you will pay $6.74 every month.
<u>2. Amount borrowed</u>
You will make a 22% down payment:
Thus the amount borrowed is $426,000 - $93,720 = $332,280
<u>3. Monthly payment</u>
Multiply the monthly payment per 1,000 by the amount borrowed divided by 1,000:
<u />
<u>4. Total monthly payments:</u>
Multiply the number of payments by the monthly payment.
Number of payments = 20 years × 12 payments /year = 240 payments.
<u>5. Total payment for the home.</u>
The total payment for the home will be the down payment plus the amount paid to the bank:
- $322,280 + $537,496 = $869,776
