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