Let X denote the length (in seconds) of the next smile of a ran- domly selected 8-week old baby. Suppose that X is uniformly distributed on the interval [0, 23]. (a) What is the probability that the next smile of a randomly selected 8-week old baby is between 15 and 25 seconds in length? (b) What is the moment generating function M(t) of X? No work is required for this part. 2.
