Use the data from Problem 15 on the diameter of Douglas fir trees.

(a) Construct and interpret a 95% confidence interval for the mean diameter of a Douglas fir tree using a bootstrap sample with 1000 resamples. Compare the bootstrap confidence interval to the t-interval found in Problem 15(c).

(b) Draw a histogram of the 1000 means. What is the shape of the histogram? Why does the result not surprise you?

(c) Construct and interpret a 95% confidence interval for the median diameter of a Douglas fir tree using a bootstrap sample with 1000 resamples?
