te cach of the following exercises, complete the ten-step hypothesis testing procedure. State the assumptions that are necessary for your procedure to be valid. For each exercise, as appropriate, olain why you chose a one-sided test or a two-sided test. Discuss how you think researchers or clinicians might use the results of your hypothesis test. What clinical or research decisions or actions do you think would be appropriate in light of the results of your test? HYPOTHESIS TESTING to engage in a variety of sports activities (multisport). The mean body mass indey for these men was 22.41 with a standard deviation of 1.27. A sample of 24 male, players had a mean BMI of 27.75 with a standard deviation of 2.64. Is there sufficient evì- 7.3.1 Subjects in a study by Dabonneville et al. (A-9) included a sample of 40 men who claimed (BMI) rugby n general, rugby players have a higher BMI than the multisport dence for one to claim that, 7.3.2 The purpose of a study by Ingle and Eastell (A-10) was to examine the bone mineral density (BMD) and ultrasound properties of women with ankle fractures. The investigators recruited 31 postmenopausal women with ankle fractures and 31 healthy postmenopausal men? Let a = = .01. women to serve as controls. One of the baseline measurements was the stiffness inder the lunar Achilles. The mean stiffness index for the ankle fracture group was 76.9 with a standard deviation of 12.6. In the control group, the mean was 90.9 with a standard deviation of 12.5. Do these data provide sufficient evidence to allow you to conclude that in general, the mean stiffness index is higher in healthy postmenopausal women than in postmenopausal women with ankle fractures? Let a = .05. uecend
