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 moundshaped 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
