Is the average time to complete an obstacle course different when a patch is placed over the right eye than when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye. Right 48 48 50 50 44 43 49 45 Left 49 50 53 51 46 48 48 45 Assume a Normal distribution. What can be concluded at the the αα = 0.01 level of significance level of significance? For this study, we should use
