The alpha for all questions is (a=.02)

In a recent study, researchers found that the national average for student loan debt among bachelor's degree recipients was $54,000 with a standard deviation of $43,000 (a very positively skewed variable). You conduct the exit surveys for your department at Ball State, and you anticipate student loan debt at BSU to be far below the national average. You find in a sample of 150 students, the average debt was $25,667. nts Use the critical-value approach for a z-test (where a = .02) to determine if there is a significant difference in debt between the national average and BSU bachelor's students. 1. State the alternative hypothesis 2. List your Z test statistic 3. List your critical value(s) 4. Is the difference between the national average and BSU bachelor's students statistically significant? (Yes/No) You also decide to look at your competition, but don't have any expectations they will be above or below the national average. You find that the average student loan debt among 230 students at Butler University is $36, 925. Use the critical-value approach for a z-test (where a = .02) to determine if there is a significant difference in debt between the national average and Butler University bachelor's students. Ins 5.
