You have two processes whose outputs are somewhat subject to uncertainty. You therefore consider the outputs to be random variables which you refer to as X and Y, respectively. You know that X and Y are independent. You dont know too much about the shapes of the distributions, but you do know that X has a mean of 8.0 and a standard deviation of 2.0. You know that Y has a mean of 3.0 and a standard deviation of 1.0. Due to the way you combine the outputs of these two processes, you need to know something about the distribution of a random variable Z = X 2Y. What are the mean and standard deviation of Z?
