Let Z be the standard normal random variable. (a) Find the value of the probability density function fx (x) of X = |Z + 11 for x = 1. (b) Find the value of the probability density function fy(y) of Y = e² for y = 2. (c) Find E[Y4] (Hint: this problem is closely related to the moment generating function for the normal distribution.)
