A college’s data about the incoming freshmen indicates that the mean of their high school GPAs was 3.4, with a standard deviation of 0.35; the distribution was roughly mound-shaped and only slightly skewed. The students are randomly assigned to freshman writing sem- inars in groups of 25. What might the mean GPA of one of these seminar groups be? Describe the appropriate sam- pling distribution model—shape, center, and spread— with attention to assumptions and conditions. Make a sketch using the 68–95–99.7 Rule
