A company with a fleet of 1500 cars found that the emissions systems of 17 out of the 53 randomly selected cars from their fleet failed to meet pollution control guidelines. If a significant number of vehicles are found to be out of compliance, the whole fleet will need to be inspected and brought up to current regulations. Is there strong evidence that more than 20% of the fleet might be out of compliance? Use a 1% level of significance. Identify Type I and II errors and their consequences.
