You do a survey of marketing students and liberal arts school students to find out how many times a week they read a daily newspaper. In each case you interview 100 students you find the following:

           a. Xm = 4.5 times per week

           b. Sm = 1.5

           c. Xla = 5.6 times per week

           d. Sla = 2.0
