Problem 19. (1 point) After 8:00pm on any Thursday, the amount of time a person spends waiting in line to get into a well-known pub is a random variable represented by X. Suppose we can model the behavior of X with the Exponential probability distribution with a mean of waiting time of 36 minutes. (a) Provide the value of the standard deviation of this distribution. Enter your answer to two decimals. OX = minutes (b) Suppose you are in line to get into the pub. Compute the probability that you will have to wait between 27 and 35 minutes to get in. Answer with four decimals. P(27
