Is the average time to complete an obstacle course faster when a patch is placed over the left eye than when a patch is placed over the right 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 51 42 49 43 41 40 47 46 55 42 50 51 39
Assume the distribution of the differences is normal. What can be concluded at the 0.10 level of significance? (d= score before - score after)
