Homework: Homework Assignment 10 Question 17, 8.3.31 Part 3 of 9 > HW Score: 74.25%6, 148.51 of 200 points Points: 7 of 10 Save Counselors at a summer camp for overweight and obese adolescents develop a weight-management program for each camper that centers on nutrition education and physical activity in a recent study, the body mass index (BMI) WAS measured for each of 78 campers both at the start and end of camo. Summary statistics on BMI measurements are shown in the table to the right. Complete parte a through h. Standard Mean Deviation Starting BMI 342 6.1 Ending BMI 300 5.7 Paired Differences 4.2 1.7 Lel a Give the null and alternative hypotheses for determining whether the mean BMI at the end of camp is less than the mean BMI at the start of camp. be the population meani BMI at the start of camp. Hy be the populalin mear BMI at the end of camp, and My Hy- Ho: Mo - Ha Hd > 0 b. How should the dela ve analyzed, as an independent samples test or as a paired ifference test? Explain. Choose the correct answer below. O A. Use a paired difference test because, although the data were not paired originally paining them atter samping significantly reduces variation within the samples. OB. Use an independent samples test because the sample of differences was chosen randomly. OC. Use an independent samples test because the sample size is greater than 30. By the Central Limit Theorem, this condion guarantees the test statistic will be approximately normal V Use a paired difference test because the Assumption of independent samples is invalid c. Calculate the test statistic using the formula for an independent samples test (This may or may not be the correct method from part b.) Thie les statistic is Round la two decinal places as needed.) - Help me solve this View an example Get more help. Clear all Check answer
