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, 10] 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? [Hint: Define rv’s X1, . . . , X10 and use a rule of expected value.]
b. What is the variance of your total waiting time?
c. What are the expected value and variance of the difference between morning and evening waiting times on a given day?
d. What are the expected value and variance of the difference between total morning waiting time and total evening waiting time for a particular week?
