Data was collected on the gas mileage (miles per gallon = MPG) for a select group of 11 SUVs; see the Excel descriptive statistics file below. After Constance viewed this data, she said "This data is very symmetrical." Clearly state why you do or why you don't agree with Constance's statement. Constance continues...

            Gasoline: Many drivers of cars that run on regular gas actually buy premium in the belief that they will get better gas mileage. To test that belief, we use 10 cars from a company fleet in which all the cars run on regular gas. Each car is filled first with either regular or premium gasoline, decided by a coin toss, and the mileage for that tankful is recorded. Then the mileage is recorded again for the same cars for...
