Many runners believe that listening to music while running enhances their performance. The authors of the paper “Effects of Synchronous Music on Treadmill Running Among Elite Triathletes” (Journal of Science and Medicine in Sport [2012]: 52–57) wondered if this was 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.
You can assume that it is reasonable to regard these 11 tri athletes 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. Do the data provide convincing evidence that the
