Suppose your waiting time for a bus in the morning is uniformly distributed on [0, 8], whereas waiting time in the evening is uniformly distributed on [0, 12] Independent of morning waiting time. (a) If you take the bus each morning and evening for a week, what is your total expected waiting time? (Assume a week includes only Monday through Friday.)

In a recent year, the mean time spent waiting for a heart transplant was 126.7 days, with a standard deviation of 21.6 days. Waiting times were normally distributed. What is the shortest waiting time that would still place a patient in the longest 15% of waiting times? Show your calculation and the answer rounded to the nearest tenth of a day.

If a person takes the bus 30 times a month commuting between his dorm and the Dining Hall. It takes the bus 10 minutes to run one loop. The waiting time, in minutes, for a bus to arrive is uniformly distributed on the interval [0, 10]. Suppose that waiting times on different occasions are independent. What is the standard deviation of the mean waiting time in minutes of a month? Round your answer to three decimal digits. What is the...
