X is a random variable having a probability distribution with a mean/expected value of E(X) = 30 and a variance of Var-(X) = 42. Consider the following random variables. A=5X B=5X1 C'=1X+9 Answer parts (a) through (0). Part (a) Find the expected value and variance of A. E(A) = E (use two decimals) Var(A) = E (use two decimals) Part (b) Find the expected value and variance of B. E(B) = E (use two decimals) Var(B) = E (use two decimals) Part (c) Find the expected value and standard deviation of C'. E(C') = E (use two decimals) 317(0) = E (use two decimals)
