5.42 The operating times in minutes of three machines are normally dis- tributed with mean times 15, 30 and 20 minutes respectively, and standard deviations 1, 2 and 5 minutes respectively. The machines are independent except for machines 2 and 3 which have operating times that are correlated with r = 0.1. What is the probability that the total operating time of the three machines is at most one hour?

A certain city the Transportation Authority (CTA) has trollies leaving regularly throughout the day beginning at 5:00 a.m. Although the length of a trip and the number of stops are constant, the time taken for each trip varies due to weather, traffic, and time of the day. According to the CTA, the mean time taken for the trip is 50 minutes. Suppose the travel time is Normally distributed with standard deviation o = 4 minutes. A random sample of 25 trips is obtained, and the time for each is recorded. Find the probability that the sample mean time will be less than 48 minutes.
