Problem 1. (1 point) X is a random variable having a probability distribution with a mean/expected value of E(X) = 24.1 and a variance of Var(X) = 36. Consider the following random variables. A=5X B=5X3 C=3X+7 Answer parts (a) through (c). Part (a) Find the expected value and variance of A. E(A) = (use two decimals) Var(A) = (use two decimals) Part (b) Find the expected value and variance of B. E(B) = (use two decimals) Var(B) = (use two decimals) Part (1:) Find the expected value and standard deviation of C. E(C) = a: (use two decimals) S D(C ) = (use two decimals) preview answers
