Consider the following 16 observed values, rounded to the nearest tenth, from the exponential distribution that was given in this section:
(a) Take resamples of size n = 16 from these observations about N = 200, times and compute s2 each time. Construct a histogram of these 200 bootstrapped values of S2.
(b) Simulate N = 200 random samples of size n = 16 from an exponential distribution with θequal to the mean of the data in part (a) minus 9. For each sample, calculate the value of s2. Construct a histogram of these 200 values of S2.
(c) Construct a q–q plot of the two sets of sample variances and compare these two empirical distributions of S2.
