A stat professor has observed that for several years about 14% of the students who initially enroll in his introduction to stats course withdraw before the end of the semester. A salesman suggests that he try a statistics software package that gets students more involved with computers, predicting that it will cut the dropout rate. The professor can use the software free of charge for one semester as a part of trail package. Initially, 181 students signed up for the statistics course. They used the software suggested, and only 10 dropped out of the course.
