ACME Fruit Distributing knows that for the last four years, the mean (or average) time it takes a particular truck to make its rounds has been 6.32 hours with standard deviation 0.41 hours. (a) Suppose you plan to observe this truck 40 times. What is the approximate distribution of the random sample mean time? Also specify its parameters. (b) What is the approximate probability that this random sample mean (with n=40) will be more than 6.7 hours?
