Sleep Time A person read that the average number of hours an adult sleeps on Friday night to Saturday morning was 7.1 hours. The researcher feels that college students sleep more than 7.1 hours on average. The researcher randomly selected 14 students and found that on average they slept 7.7 hours. The standard deviation of the sample is 1.3 hours. At a=0.05, is there enough evidence to say that college students sleep more than 7.1 hours on average?

![**Sleep Time Study**
A person read that the average number of hours an adult sleeps on Friday night to Saturday morning was 7.1 hours. The researcher feels that college students sleep more than 7.1 hours on average. The researcher randomly selected 14 students and found that on average they slept 7.7 hours. The standard deviation of the sample is 1.3 hours. At \(\alpha = 0.05\), is there enough evidence to say that college students sleep more than 7.1 hours on average? Assume that the population is approximately normally distributed. Use the *P*-value method and tables.
**Part 1 of 5**
(a) State the hypotheses and identify the claim.
- \(H_0: \mu = 7.1\) (not claim)
- \(H_1: \mu > 7.1\) (claim)
This hypothesis test is a **one-tailed** test.
**Part: 1 / 5** [Progress bar indicating the completion of part 1 of 5 parts]
**Part 2 of 5**
(b) Compute the test value. Always round *t* score values to three decimal places.
