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 48 47 45 46 40 49 46 48 Left 48 46 43 41 43 50 45 49 Assume a Normal distribution. What can be concluded at the the a = 0.05 level of significance level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Ho: Select an answer H₁: Select an answer Select an answer C Select an answer O Select an answer Select an answer = (please enter a decimal) (Please enter a decimal) b.

(please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) 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. O 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 greater than the population mean time to complete the obstacle course with a patch over the left eye. O The results are statistically significant at a = 0.05, 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 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 = 0.05, 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.

Transcribed Image Text: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.

O 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 obstaclè course with a patch over
the left eye.
(Please show your answer to 4 decimal places.)
O 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
greater than the population mean time to complete the obstacle course with a patch over the left
eye.
O The results are statistically significant at a = 0.05, 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
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 = 0.05, so there
that the eight volunteers that were completed the course slower on average with the patch over
sufficient evidence to conclude
the right eye compared to the left eye.
