Is the average time to complete an obstacle course longer 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 45 49 50 42 42 45 46 42 Left 42 45 47 41 42 43 48 39 Assume a Normal distribution.  What can be concluded at the the αα = 0.01 level of significance level of significance? (Define μdμd to be the "right-eye" mean time minus the "left-eye" mean time.)
