Absenteeism of college students from math classes is a major concern to math instructors because missing class appears to increase the drop rate. Suppose that a study was done to determine if the actual student absenteeism follows faculty perception. The faculty expected that a group of 100 students would miss class according to the following chart. Number of absences per term Expected number of students 0-2 50 3-5 30 6-8 12 9+ 8 A random survey across all mathematics courses was then done to determine the actual number (observed) of absences in a course. The next chart displays the result of that survey.

1. Absenteeism of college students from math classes is a major concern to math instructors because missing class appears to increase the drop rate. Suppose that a study was done to determine if the actual student absenteeism follows faculty perception. The faculty expected that a group of 100 students would miss class according to the following chart. Number of absences per term Expected number of students 0-2 50 3-5 30 6-8 12 9+ 8 A random survey across all mathematics courses was then done to determine the actual number (observed) of absences in a course. The next chart displays the result of that survey. Number of absences per term Actual number of students 0-2 35 3-5 20 6-8 40 9+ At 5% level of significance, test the claim that student absenteeism fits faculty perception.
