1.Ten cars were equipped with radial tires and driven over a test course. Then the same 10 cars (with the same drivers) were equipped with regular belted tires and driven over the same course. After each run, the cars' gas economy (in mpg) was measured.We would like to predict the regular MPG from the radial MPG.
