Chapter , Problem 16.52(choose chapter or problem)
The correlation between GPA and high school math grades. The study described in Example 16.4 (page 16-14) used high school grades to predict GPA. For this exercise, we will look at the correlation between GPA and high school math grades. GPA (a) Describe the distribution of GPAs. Do the same for high school math grades. (b) Describe the relationship between GPA and high school math grades. (c) Generate 2000 resamples and use these to obtain the bootstrap distribution for the correlation. (d) Describe the shape and bias of the bootstrap distribution. Does use of the simpler bootstrap confidence intervals (t and percentile) appear to be justified?
