In a random sample taken from 3 high schools in Albany area the mean GPA of female seniors (N = 526) is 2.92 with the standard deviation of 1. The mean GPA of male seniors (N = 477) is 2.77 with the standard deviation of 1.2. If you want to test whether female high school seniors in Albany (Sample 1) have lower GPA than male high school seniors (Sample 2), your alternative hypothesis would be: %3D %3D O H1: µ1 < µ2 O H1: µ1 # 2.77 O H1: µ1 > µ2 H1: µ1 # p2
