A college's provost (chief academic ofcer) selects a random sample of 5 students' overall grade point averages [GPAs) in each of 8 consecutive semesters. These sample GPAs along with their sample means (:72), sample ranges (R), and sample proportions [15) are given in the table below. (FYI: Any GPA that is less than 2.0 was considered "defective" in the calculation of the 15 statistics for each subgroup.)
