Example 22: Find the moment generating function of the random variable whose moments are m,= (r+ 1) ! 2".

Question 4 Let X be a random variable with AX) 0, EX) 0.6. if x 1 Answer (1) and (2): (1) If X, X2, X3, X4 are iid f, then (i) PX4) S0.8) = (.. ..). (ii) PX1) < 0) = (...). (2) Let X, X2,.., X36 be iid f You are given: PZS 1.96) = 0.975; P(ZS 2) = 0.977; P(Z< 1.55) 0.939, PZS 1.81) = 0.965. Use the CLT to approximate PXS 0.2). %3D %3D %3D
