In a certain manufacturing process, the (Fahrenheit) temperature never varies by more than 2o from 62o. The temperature is, in fact, a random variable F with distribution



(a) Find E (F) and V (F).
(b) Define T = F − 62. Find E (T) and V (T), and compare these answers with those in part (a).
(c) It is decided to report the temperature readings on a Celsius scale, that is, C = (5/9)(F − 32). What is the expected value and variance for the readings now?
