The dean of a university estimates that the mean number of classroom hours per week for full-time faculty is 11.0. As a member of the student council, you want to test this claim. A random sample of the
number of classroom hours for eight full-time faculty for one week is shown in the table below. At a = 0.10, can you reject the dean's claim? Complete parts (a) through (d) below. Assume the population is
normally distributed.

(c) Decide whether to reject or fail to reject the null hypothesis.
Which of the following is correct?
O A. Fail to reject Ho because the P-value is less than the significance level.
O B. Reject Ho because the P-value is greater than the significance level.
OC. Reject Ho because the P-value is less than the significance level.
O D. Fail to reject Ho because the P-value is greater than the significance level.
(d) Interpret the decision in the context of the original claim.
