A taxi company manager is trying to decide whether the use of radial tires instead of regular belted tires improves fuel economy. Twelve cars were equipped with radial tires and driven over a prescribed test course. Without changing drivers, the same cars were then equipped with regular belted tires and driven once again over the test course. The gasoline consumption, in kilometers per liter, was recorded as follows:
Kilometers per Liter Car123456789101112Radial Tires4.24.76.67.06.74.55.76.07.44.9 6.15.2Belted Tires4.14.96.26.96.84.45.75.86.94.7 6.04.9
Can we conclude that cars equipped with radial tires give better fuel economy than those equipped with belted tires? Assume the populations to be normally distributed. Use a P-value in your conclusion.
