Is the average time to complete an obstacle course shorter 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.

the eight volunteers that were completed the course faster on average with the patch over the right
eye compared to the left eye.
