Metropolitan University conducts course assessment each year to monitor the proportion of students who do not meet the minimum passing score on a comprehensive exam given at the end of the students’ academic program. The results are used as an improvement tool. The passing score is 70%. On average 200 students take the assessment exam each semester. The table below shows the number of students who passed the assessment exam during the last 10 semesters: Semester # of students who passed 1 180 2 185 3 175 4 190 5 192 6 190 7 188 8 178 9 200 10 194 a.
