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. You can 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 0.05. (Use $\mu_D = \mu_{music} - \mu_{no \ music}$) $H_0: \mu_D \le 0$ $H_a: \mu_D > 0$ Find the test statistic.

A person can have an XY genotype (genetic male), have no apparent testicles, and identify as a female for her entire life. This describes a condition called androgenic insensitivity syndrome. This condition exemplifies: Group of answer choices A) genetic sex does not always determine gender identity (or phenotype) B) genetic sex causes homosexuality C) genetic sex determines gender identity D) genetic sex does not usually influence phenotype
