The same study found that the national average for student loan debt among graduate degree recipients was $93,000 with a standard deviation of $63,000. In this case, you know less about the graduate programs, and do not have any expectations for BSU debt being higher or lower than the national average. You find in a sample of 81 students, the average debt was $78,000. Use the p-value approach for a z-test (where a = .07) to determine if there is a significant difference in debt between the national average and BSU graduate students. 9. State the alternative hypothesis 10. List your Z test statistic 11. List your p value (be sure to double p values for nondirectional tests) 12. Is the difference between the national average and BSU graduate degree holders statistically significant? (Yes/No) Hypothesis Testing Decisions and Errors 13. When testing whether graduate students take significantly longer to pay off student debt than average, you study concluded they did take longer. In reality, the difference your test detected does not exist. This is an example of what kind of hypothesis testing decision? 14. When testing whether college students make significantly more money than others on average, you study concluded they did have higher incomes. In reality, the difference your test detected does exist. This is an example of what kind of hypothesis testing decision
