The dean of a university estimates that the mean number of classroom hours per week for full-time facuity is 11.0. 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 α=0.05, can you reject the dean's claim? Complet parts (a) through (d) below Assume the population is normally distributed. 11.1
