Question

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.

Time to Complete the Course

Right 48 44 47 40 46 41 46 48
Left 45 42 45 36 45 35 44 45

Assume a Normal distribution.  What can be concluded at the the αα = 0.10 level of significance level of significance?

For this study, we should use       

  1. The null and alternative hypotheses would be:   
  2.   

 `0:`                      

 `a:`                   

2. The test statistic     =  (please show your answer to 4 decimal places.)

3. The p-value =  (Please show your answer to 4 decimal places.)
