Step 1

We are given null and alternative hypothesis.

Null hypothesis:

Ho: μ ≤ 7

And alternative hypothesis:

Ha: μ > 7

Step 2

We know when we have given any claim that can be write down in null hypothesis or alternative hypothesis.

We will validate each of the given option.

1. a) A study wants to show that the mean number of hours of sleep the average person gets each day is at least 7.

This means that μ ≥ 7

Which is not given in null or alternative hypothesis, so it is not a valid option.

Step 3
1. b) A study wants to show that the mean number of hours of sleep the average person gets each day is 7.

This means that μ = 7

Which is not given in our hypothesis, so it is also not valid option.

1. c) A study wants to show that the me...
