Suppose you are a quality assurance manager for Honda. A new model of family car has been built, and the engineers are interested in testing the new model to ensure it meets Canadian safety standards. The safety standards indicate that the vehicle must be able to stop within 17.38 metres from a speed of 48.3 km/h [1]. Note this means the quality assurance team wants to ensure the cars stop in less than 17.38 metres on average). They obtain a random sample of 21 new model cars, and test the brakes on each car. The sample mean stopping distance from this sample of 21 cars is 17 metres. Suppose the population standard deviation is 1.25 metres. Conduct an appropriate hypothesis test using the critical value method. Based on your answer to part a.,do you believe the company can sell the new model car in Canada? Why or why not?
