D Question 22 4 pts Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. A coach uses a new technique in training middle distance runners. The times for 8 different athletes to run 800 meters before and after this training are shown below. Athlete ABCDEFGH Time before training (seconds 118.3 115.8 108.9 111.8 116.5 108.6 115.2 119.8 Time after training (seconds 118.9 114.5 106.5 112.6 114.7 108.7 111.6 115.9 Using a 0.05 level of significance, test the claim that the training helps to improve the athletes' times for the 800 meters. Reject Ho if the test statistic is greater than 2.365 Reject Ho if the test statistic is less than -1.860 Reject Ho if the test statistic is greater than 1.895 Reject Ho if the test statistic is less than -1.645
