Is the average time to complete an obstacle course longer 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 43 47 48 49 50 41 47 49
Left 42 45 47 45 46 43 47 49
Assume a Normal distribution. What can be concluded at the the a = 0.10 level of significance level of
significance?

Select an answer the null hypothesis.
O The results are statistically insignificant at a = 0.10, 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 greater than the population mean time to complete the obstacle course with a
patch over the left eye.
The results are statistically significant at a = 0.10, 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 greater than the population mean time to complete the obstacle course with a patch over
the left eye.
The results are statistically insignificant at a = 0.10, 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 significant at a = 0.10, so there is sufficient evidence to conclude
that the eight volunteers that were completed the course slower on average with the patch
over the right eye compared to the left eye.
