Answer:

Step-by-step explanation:

Thus, the 95% confidence interval for the mean GPA for the entire population of graduating students at this university is approximately (2.681, 2.959)(2.681,2.959).

In this study, N, the population size, is not explicitly given. However, since the researcher is interested in the mean GPA for the entire population of graduating students, we can assume N refers to the total number of graduating students at the university.
