1. Simulate an 80% coverage probability for thet-interval estimator of the true/pop’nµforn=7,15.

3) Compare your result above with the 90% bootstrap percentile interval.

4) Draw random samples of size 20 from Gamma(5, 2) to see how often the t confidence interval for the mean misses the true mean. Repeat this simulation by changing the sample size, say, n = 10, n = 40, n = 100, and n = 250. How does the sample size affect the frequency of missing ???
