1) state your hypotheses; 2) draw a graph showing the critical z-scores and the rejection region; 3) calculate z-obtained; 4) make a conclusion.

1. Does college experience depend on one’s major? The mean satisfaction with college experience in a random sample of 48 math majors is 8.3 with a standard deviation of 2. The mean satisfaction with college experience of all students in the previous year is 7.8. Are math majors different from all other students in terms of their college satisfaction? Use α=0.01.
