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.

Assume a Normal distribution. What can be concluded at the the a = 0.05 level of significance level of
significance?

(Please show your answer to 4 decimal places.)
O
Select an answer the null hypothesis.
The results are statistically insignificant at a = 0.05, so there is statistically significant evidence
to conclude that the population mean time to complete the obstacle course with a patch over the
right eye is equal to the population mean time to complete the obstacle course with a patch over
the left eye.
The results are statistically insignificant at a = 0.05, so there is insufficient evidence to conclude
that the population mean time to complete the obstacle course with a patch over the right eye is
less than the population mean time to complete the obstacle course with a patch over the left
eye.
The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude
that the eight volunteers that were completed the course faster on average with the patch over
the right eye compared to the left eye.
The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude
that the population mean time to complete the obstacle course with a patch over the right eye is
less than the population mean time to complete the obstacle course with a patch over the left
eye.
