A researcher at a large university is interested in the GPAs of graduating students. The researcher gathers a sample of 30 graduating students. They find that the sample mean GPA is 2.82 with a sample standard deviation of 0.39. Construct the 95% confidence interval for the mean GPA for the entire population of graduating students at this university. What is N in this study?



Answer :

1604332

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.
