Use a t-test to investigate the claim and assume that the population is normally distributed:
A large university says the mean number of classroom hours per week for full-time faculty is more than 9. A random sample of the number of classroom hours for full-time faculty for one week is listed. At alpha = 0.05 , test the university's claim.
