Suppose that an airline quotes a flight time of 2 hours, 10 minutes between two cities. Furthermore, suppose that historical flight records indicate that the actual flight time between the two cities, x, is uniformly distributed between 2 hours and 2 hours, 20 minutes (uniform distribution). Letting the time unit be one minute, What is the mean? What is the standard deviation? Find P(125 ≤ x ≤ 135) (between 125 minutes and 135 minutes).
