The engineers at a car company want to test the speedometer on a new car model. They selected a random sample of 40 of these cars, and the actual speed for each car was determined using a radar device when the speedometer registered 50 mph. The resulting 99% confidence interval was (51.2, 52.3). To test if the mean actual speed
