    Conduct a computer simulation to generate the sample means of Poisson random variables. First generate X ∼ Poisson(3), and plot a histogram of this Poisson random variable. Then generate X = 1/5(X1 + X2 + X3 + X4 + X5), where X1, X2, . . . , X5 are all from Poisson(3). Plot a histogram of this sample mean statistic X. Compare the histograms and describe the changes you see in the histograms. Explain the changes using Central Limit Theorem....
