Question: A university recently completed a study to determine whether the number of classes students dropped during their college course work was related to whether the student lived on campus or commuted. The following data were collected.

                                             Where Lived

Courses dropped           Commuted           On Campus

          0                          70                      90

          1                          60                      50

          2                          45                      28

          3                          42                      47

      Over 3                       36                      48

Using an = 0.05 level, determine whether the number of courses dropped is independent of where a student lives.
