The amount of time that a truck spends in waiting at the distribution center for unloading is a random variable with a mean of 30 minutes and a standard deviation of 20 minutes. Suppose that a random sample of 9 trucks is observed. Find the probability that the average waiting time of trucks is: (1) Less than 20 minutes (2) Between 20 and 40 minutes
