95% confidence, develop an interval estimate for the difference between the average miles per gallon for the two models. b. Is there conclusive evidence to indicate that one model gets a higher miles per gallon than the other? If yes, explain how you know this and which model is higher. If no, explain how you know that there is not enough evidence.
