Use the following information to answer the next four exercises. Two students are interested in whether or not there is variation in their test scores for math class. There are 15 total math tests they have taken so far. The first student's grades have a standard deviation of 38.1. The second student's grades have a standard deviation of 22.5. The second student thinks his scores are more consistent. 10. State the null and alternative hypotheses. 11. What is the F Statistic? 12. What is the critical value? 13. At the 5% significance level, do we reject the null hypothesis?
