The article "So Close, Yet So Far: Predictors of Attrition in College Seniors" attempts to describe differences between college seniors who dis-enroll before graduating and those who do graduate. Researchers randomly selected 42 non-returning and 48 graduating seniors, none of whom were transfer students. These 90 students rated themselves on personal contact and campus involvement. The resulting data is summarized here: Returning n= 48 Mean Standard Deviation Nonreturning n= 42 Mean Standard Deviation Personal Contact 3.22 93 Personal Contact 2.41 1.03 Campus Involvement 3.21 1.01 Campus Involvement 3.31 1.03 Construct a 95% confidence interval for the difference in mean campus involvement rating for returning and non-returning students. Does your interval support the statement that students who do
