(1) Using a generator for a binomial distribution, we will test the results of Example 3.8.2. Using software generate 500 random deviates for X from a B(10, 0.3) distribution and 500 random deviates for Y from a B(5, 0.3) distribution. Add corresponding random deviates from each distribution to form an empirical W=X+Y. Then use the theoretical result of Example 3.8.2 and directly generate another 500 random deviates for W from a B(15, 0.3). Order the result of the sum of...
