"It is claimed that a car is driven on the average less than 18100 kilometers per year with a population standard deviation of 2500 kilometers. A company wants to test if their current car model is on par with this average. To test this, a random sample of 59 cars from the company were tested. Suppose you are an analyst of the company, would you suggest to make improvements in your car design if the random sample showed an average of 18500 kilometers? Use a 0.01 level of significance." I will be certain that there is no need to improve the car design based on the result. B I would recommend an improvement to the car design to improve performance. I will assume that the cars are on par with the average and recommend to do nothing. There is no sufficient data to make a sound conclusion.
