Use the following information to answer the next three exercises. Two cyclists are comparing the variances of their overall paces going uphill. Each cyclist records his or her speeds going up 35 hills. The first cyclist has a variance of 23.8 and the second cyclist has a variance of 32.1. The cyclists want to see if their variances are the same or different. Assume that commute times are normally distributed. 14. State the null and alternative hypotheses. 15. What is the F Statistic? 16. At the 5% significance level, what can we say about the cyclists' variances?
