3. The duration of a cellular telephone call is an exponential random variable X with expected value E(X) = 2.5 minutes. Assume that the durations of all phone calls are mutually independent and that the telephone company measures call duration exactly and charges accordingly, without rounding up fractional minutes. (a) In a certain month, a subscriber has 120 cellular calls. Let T be the total amount of time spent on the phone by the subscriber. What is the expected value and variance of T? (b) The subscriber has a calling plan that includes 300 minutes per month at a cost of $30.00, plus $0.40 for each minute that the total calling time exceeds 300 minutes. Use the central limit theorem to estimate the probability that subscriber's bill is greater than $36.
