Consider the Octane dataset. A researcher randomly selected 11 individuals (and their cars) to participate in a study. Each participant received 10 gallons of gas and drove their car on a closed course that simulated both city and highway driving. The number of miles driven until the car ran out of gas was recorded. A coin flip was used to determine whether the car was filled with 87-octane or 92-octane fuel first, then the process was repeated with the other type of fuel. The driver did not know which type of fuel was in his or her tank on each run. Run the appropriate Hypothesis Test to test the claim that the mileage from the 87-octane gas is actually less than the mileage from the 92-octane gas. What is your test statistic
