The mean of the sum (or difference) of two independent random variables equals the sum (or difference) of their means, but the variance is always the sum of the two variances. Use random number generation to verify this statement for the case where zx +y where x and y are independent and normally distributed random variables. The mean and variance of x are Hx 8 and ơi-2. The mean and variance of y are y-15 and ơ-4. Find the mean and variance of z by simulation, and compare the results with the theoretical prediction. Do this for 100, 1000, and 5000 trials.
