It is best to use an experiment, because most cars will use compressed air and not nitrogen. Thus we would not have a lot of available data for the nitrogen case.
Choose randomly a few cars of each brand. Half of the cars for each brand will be in group 1, while the other cars are in group 2.
Group 1 will have their tires filled with nitrogen, while Group 2 will have their tires filled with compressed air.
Then determine the gas mileage for a full tank for each car and compare the results the two groups.
