Many runners believe that listening to music while running enhances their performance. The authors of a paper wondered if this is true for experienced runners. They recorded time to exhaustion for 11 triathletes while running on a treadmill at a speed determined to be near their peak running velocity. The time to exhaustion was recorded for each participant on two different days. On one day, each participant ran while listening to music that the runner selected as motivational. On a different day, each participant ran with no music playing. For purposes of this exercise, assume that it is reasonable to regard these 11 triathletes as representative of the population of experienced triathletes. Only summary quantities were given in the paper, but the data in the table below are consistent with the means and standard deviations given in the paper.

Test the relevant hypotheses using a significance level of α = 0.05. (Use μd = μmusic − μno music.) State the appropriate null and alternative hypotheses. Find the test statistic and P-value. (Use a table or technology. Round your test statistic to two decimal places and your P-value to three decimal places.) t = P-value =
