(choose chapter or problem)

Compare the correlations. In Exercise 16.51 (page 16-41) we compared the mean GPA for men and women using the bootstrap. In Exercise 16.52 we used the bootstrap to examine the correlation between GPA and high school math grades. Lets find the correlations for men and women separately and ask whether there is evidence that they differ. GPA (a) Find the correlation between GPA and high school math grades for the men. Use the bootstrap to find a 95% confidence interval for the population correlation. (b) Repeat part (a) for the women. (c) Use the bootstrap to test the null hypothesis that the population correlations for men and women are the same, rMen rWomen . (d) Summarize your findings.
