taxi company is trying to decide whether to purchase brand A or brand B tires for its fleet of taxis. To estimate the difference in the two brands, an experiment is conducted using 16 of each brand. The tires are run until they wear out. The results are given in the table below. Compute a 95% confidence interval for μA−μB assuming the populations to be approximately normally distributed. You may not assume that the variances are equal. Brand A x1=35,300 kilometers s1=5100 kilometers Brand B x2=37,300 kilometers s2=6600 kilometers
