The “fear for negative evaluation” score for 17 female students
known to suffer from the
eating disorder bulimia, and 14 female students with normal eating
habits were compared to
determine whether the distribution of the scores for Bulimic female
students ( population A)
is shifted to the right of the corresponding distribution for
female students with normal eating
habits. (population B) If T2 = 148 conduct the test and give the
conclusion, using a level of
significance of 0.06.
There is insufficient evidence to conclude that the distribution of the scores for Bulimic female students ( population A) is shifted to the right of the corresponding distribution for female students with normal eating habits.

The mean exam score for 44 male high school students is 20.1 and the population standard deviation is 4.7. The mean exam score for 58 female high school students is 19.6 and the population standard deviation is 4.1. At a = 0.01, can you reject the claim that male and female high school students have equal exam scores? Complete parts (a) through (e).
