Researchers wondered what the average braking distance is for new cars traveling at 60 MPH. They randomly sampled 40 new cars made by two different companies. For each car, the same driver obtained a speed of 60 MPH and then pushed on the brake pedal as hard as she could. The average stopping distance for these 40 cars was 155.2 feet. Suppose sigmais known to be 12 feet. Assume that braking distances of the cars is independent. Are the other conditions satisfied to use the one-sample z-methods to construct a confidence interval?
