A new composition for car tires has been developed and is being compared with an older composition. 3 tires are manufactured from the new composition, and 3 tires are manufactured from the old composition. One tire of the new composition and one of the old composition are placed on the front wheels of each of 3 cars, Which composition goes on the left or right wheel is determined randomly. The wheels are properly aligned. Each car is driven 35,000 miles under a variety of driving conditions. Then the amount of wear on each tire is measured. Do the results show at the 5% level of significance that the old composition gives significantly more wear than the new composition? Please do a paired, one-tailed t-test.
