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. G 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 (2.2658, 9.1342). (Round to two decimal places as needed.)
