During a recent gasoline shortage, according to a random sample of 45 cars, the average wait time before filling gas at the local station was five and a half minutes. However, the owner of the gas station claimed that the average time spent by customers was five minutes. Use a value of 2% for the probability of a Type 1 error. If the standard deviation is 1.7 minutes per car, determine the following: a. Is there enough evidence from the sample of 45 cars to refute the gas station owner's claim? Explain the reason for your answer. b. What is the p-value based the information given above? Show how you determined the answer. c. Repeat part 'a' if the five and a half minute average wait time was based on 100 random cars.
