Female college student participation in athletics has increased dramatically over the past few decades. Sports medicine providers are aware of some unique health concerns of athletic women, including disordered eating. A study compared disordered-eating symptoms and their causes for collegiate female athletes (in lean and nonlean sports) and nonathletes. The sample mean of the body dissatisfaction assessment score was 13.1 (s = 8.1) for 17 lean sports athletes (those sports that place value on leanness, including distance running, swimming, and gymnastics) and 7.4 (s = 5.9) for the 69 nonlean athletes. Assume equal population standard deviations. Complete parts a and b below. a. Find the standard error for comparing the means. se 1.727 (Round to three decimal places as needed.) b. Construct a 95% confidence interval for the difference between the mean body dissatisfaction for lean sport athletes and nonlean sport athletes. Interpret. The 95% confidence interval is (2.27, 9.13). (Round to two decimal places as needed.) Interpret the confidence interval. Choose the correct answer below. OA. There is a 95% chance the difference in mean body dissatisfactions for lean sport athletes and nonlean sport athletes is between the two interval bounds. OB. There is a 95% chance the difference in mean body dissatisfactions for lean sport athletes and nonlean sport athletes is outside the two interval bounds. O C. With 95% confidence, one can estimate that the difference in mean body dissatisfactions for lean sport athletes and nonlean sport athletes is outside the two interval bounds. O D. With 95% confidence, one can estimate that the difference in mean body dissatisfactions for lean sport athletes and nonlean sport athletes is between the two interval bounds.
