C! A taxi company is trying to decide whether to purchase brand A or brand B tires for its feet of taxis. To estimate the difference in the two brands, an experiment in conducted using 8 of each brand, assigned at random to the left and right rear wheels of 8 taxis. The tires are run until they wear out and the distances, in kilometers, are recorded in the accompanying data set. Find a 95% confidence interval for He-Assume that the difference of the distances are approximately normally distributed Click here to view the data set Click here to view page 1 of the table of critical values of the distribution Click here to view page 2 of the table of critical values of the t distribution Let 4 be the population mean for brand A and let y be the population mean for brand B. The confidence interval is - 7527.6
