Supplier delivery times.  Supplier on time delivery performance is critical to enabling the buyer’s organization to meet its customer service commitments.  Therefore, monitoring supplier delivery times is critical.  Based on a great deal of historical data, a manufacturer of personal computers finds for one of its just-in-time suppliers that the delivery times are random and well approximated by the Normal distribution with mean 48.2 minutes and standard deviation 13.4 minutes.  What is the probability that the mean time of 5 deliveries will exceed one hour?
