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.
