Compute E((X - m)(X - m)(X - m)(X - m)), the expected value of the fourth power of (X - m), for the case where m = E(X) = 1, E(X squared) = 3, E(X cubed) = 9, and E(X to fourth) = 30.
a. 16 b. 3 c. 9 d. 12 e. 4
Consider:
Taking expectation both sides, we get:
Thus, the correct answer is c. 9 [ANSWER]
