A taxi company is trying to determine whether the use of radial tires and belted tires provide the same fuel consumption. Twelve cars were driven twice over a prescribed test course; and for each test a car used a different type of tire (radial or belted) in random order. The data were: Type of tire RADIAL with(Mean = 5.75 Standard deviation = 1.10) and BELTED with(Mean = 5.61 Standard deviation = 1.30). a)what statistic is most applicable? b)the null hypothesis is? c)the degree of freedom is? d)the critical value is? e)the computed statistic value is? f) the final decision is?
