Test of Two Variances · Exercise 15

Two cyclists are comparing the variances of their overall paces going uphill. Each cyclist records their 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.
