If you take the bus each morning and evening for aweek, what is your total expected waiting time?[Hint: Define rvs X1, . . . , X10 and use a rule ofexpected value.]b. What is the variance of your total waiting time?c. What are the expected value and variance of the differencebetween morning and evening waiting timeson a given day?d. What are the expected value and variance of the differencebetween total morning waiting time and totalevening waiting time for a particular week?
