(b) Find the critical value(s) and identify the rejection region(s),

(c) Calculate d-and sd,

(d) Find the standardized test statistic t,

(e) Decide whether to reject or fail to reject the null hypothesis,

(f) Interpret the decision in the context of the original claim. Assume the samples are random and dependent, and the populations are normally distributed. If convenient, use technology.

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 a =0.10, 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. (a) Identify the claim and state Ho and Ha What is the claim? O A. Using Vitamin C decreases muscular endurance. i Repetitions Data X B. Using Vitamin C increases muscular endurance O C. Using a placebo increases muscular endurance. Participant Repetitions Repetitions O D. Using a placebo decreases muscular endurance. (using (using Vitamin C placebo) Let Ho be the hypothesized mean of the difference in the number of repetitions (placebo - Vitamin C). What are Ho and Ha? 430 707 71 990 O A. Ho: Hd = 0 O B.
