(4 points) The random variable X has moment generating function px(t) - (1 - 0.2t) ,t

(4 points) The random variable X has moment generating function 4x(t) Provide answers to the following to two decimal places (1 - 0.20- 0.2 (a) Evaluate the natural logarithm of the moment generating function of 4X at the point t = 0.16 (b) Hence (or otherwise) find the expectation Of 4X. (c) Evaluate the natural logarithm of the moment generating function of 4X + 5 at the point t Note: You can ear partial credit on this problem. = 0.16.
