# Question

Do older college baseball players tend to weigh more than younger baseball players? Our data are ages and weights for a random sample of 24 college baseball players. A scatterplot (not shown here) shows that the association between age and weight is linear. Refer to the Minitab output given.

a. Do weights tend to be larger or smaller for older students in this sample? Explain.

b. Use the Minitab output to test the hypothesis that the slope is zero using a significance level of α = 0.05. Show all four steps of the hypothesis test, and explain your conclusion. Assume that all the required conditions are satisfied. The statistics for the test of the hypothesis that the slope is 0 are in the row labeled “Age.”
