A physical therapist claims that one 600-milligram dose of Vitamin C will increase muscular endurance. The table available below shows the numbers of repetitions. 15 males made on a hand dynamometer (measures grip strength) until the grip strengths in three consecutive trials were 50% of their maximum grip strength. At α = 0.05, is there enough evidence to support the therapist's claim? Assume the samples are random and dependent, and the population is normally distributed. Complete parts (a) through (e) below. Click the icon to view the repetitions data.
