Many drivers of cars that can run on regular gas actually buy premium in the belief that they will get better gas mileage. to test that belief, 10 cars in a company fleet were used. all the cars run on regular gas. each car was filled first with either regular or premium gasoline, decided by a coin toss. the mileage for that tank of gas was recorded. then the car was filled with the other type of gasoline and the mileage for that tank of gas was recorded. the difference in gas mileage between the two types of gasoline (premiumminusregular) for the 10 cars was recorded. a 95% confidence interval was constructed using the paired t-methods: (0.5,3.5) mpg. which of the following is the correct interpretation of this confidence interval?
