An auto magazine wants to compare the battery range of two highly completive cars. As cars are expensive, each manufacturer gives them 10 cars to test. The first manufacturer has an average battery range of 408 miles with a standard deviation of 10 miles. The second manufacturer has a range of 398 miles with a standard deviation of 40 miles.
