Aconsumer advocate conducted a test of a popular gasoline additive that was claimed to increase gasoline mileage in cars. for a sample of 15 cars they used the additive and determined how many more miles the car could drive when the additive was added to the gas tank. for example, a positive 10 would mean that the car drove 10 more miles with the additive whereas a -3 would mean that the car drove 3 fewer miles with the additive. the table shows a few data values (of how many more miles a car could drive with the additive) along with some summary statistics. are there any striking deviations? a) -5 b) -3 c) 37 d) 65
