Question 2 (5 points) A coach wants to test the effectiveness of the new type of training proposed by comparing the average times of 11 runners in the 100 meters. Are below the time in seconds before and after training for each athlete. Before training: 12.9, 13.5, 12.8, 15.6, 17.2, 19.2, 12.6, 15.3, 14.4, 11.3, 12.1 After training: 12.7, 13.6, 12.0, 15.2, 16.8, 20.0, 12.0, 15.9, 16.0, 11.1, 11.9 In this case we have two sets of paired samples, since the measurements were made on the same athletes before and after the workout. Test if the new type of training has improved the results or not. Keep in mind that you need to write down your hypothesis before testing it
