Chapter 13, Problem 28SE

Weights of Athletes Data were collected on the weights of 25 male baseball players and 25 male soccer players. Assume that these are random samples from all college baseball and soccer players. Refer to the Mann-Whitney output. Assume the shapes and spreads of the two distributions are the same.

a. Which group tends to weigh more in this sample? Compare the median weights by referring to the output.

b. Are these data paired or independent? Explain.

c. Test the hypothesis that the median weights are different. Use a 0.05 significance level, and use the Mann-Whitney test.
