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

Left

Assume a Normal distribution. What can be concluded at the the a = 0.01 level of significance level of
significance?
For this study, we should use t-test for the difference between two dependent population means
a. The null and alternative hypotheses would be:
Ho: pd
(please enter a decimal)
H1: ud
v (Please enter a decimal)
>
b. The test statistic t
-0.261
(please show your answer to 3 decimal places.)
c. The p-value = 0.4008
(Please show your answer to 4 decimal places.)
d. The p-value is >va
e. Based on this, we should fail to reject
f. Thus, the final conclusion is that ...
v the null hypothesis.
O The results are statistically significant at a = 0.01, 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.
O The results are statistically insignificant at a = 0.01, 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.
O The results are statistically significant at a = 0.01, 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.
O The results are statistically insignificant at a = 0.01, 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.
