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 46 46 43 44 47 44 43 48 Left 46 49 45 45 47 47 50 50 Assume a Normal distribution. What can be concluded at the the αα = 0.05 level of significance level of significance? The test statistic T = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.)
