Question: Suppose X and Y are random variables with E(X) =10, std dev (X) = 3, E(Y) =15, and std dev (Y)= 4. Given that X

Suppose X and Y are random variables with E(X) =10, std dev (X) = 3, E(Y) =15, and std dev (Y)= 4. Given that X and Y are independent, what are the mean and standard deviation of the random variable X - Y? Explain exactly how you calculated your final answer.
