Are college students who take a freshman orientation course
more or less likely to stay in college than those who do not take such a
course? The article “A Longitudinal Study of the Retention and Academic
Performance of Participants in Freshmen Orientation Courses” (Journal of
College Student Development : 444– 449) reported that 50 of 94 randomly
selected students who did not participate in an orientation course returned for
a second year. Of 94 randomly selected students who did take the orientation
course, 56 returned for a second year. Construct a 95% confidence interval for 1
– 2, the difference in the
proportion returning for students who do not take an orientation course and
those who do. Give an interpretation of this interval.
