Generate 20 observations from a g-and-h distribution with g = h = .5. (This can be done with the R or S-PLUS function ghdist, written for this book.) Examine a boxplot of the data. Repeat this 10 times. Comment on the strategy of examining a boxplot to determine whether the confidence interval for the mean has probability coverage at least as high as the nominal level.
