Question
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 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. E Click the icon to view the repetitions data. O E. Ho: Hd #0 F. Ho: Hd 20 O D. Ho: Hd 2d Ha: Hd <d Ha: Hd =0 Ha: Hd <0 (b) Find the critical value(s) and identify the rejection region(s). Select the correct choice below and fill in any answer boxes to complete your choice. (Round to three decimal places as needed.) O A. t< or t> O B. t> VC. t< -1.345 (c) Calculate d and s. d = (Round to one decimal place as needed.)
