A taxi company is trying to decide whether to purchase brand A or brand B tires for its fleet of taxis. To esti- mate the difference in the two brands, an experiment is 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 kilome- ters, are recorded in the accompanying data set. Find a 99% confidence interval for u1- p2. Assume that the differences of the distances are approximately normally distributed. Figure 1: A picture of a gull.

Question
A taxi company is trying to decide whether to purchase brand A or brand B tires for its fleet of taxis. To esti- mate the difference in the two brands, an experiment is 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 kilome- ters, are recorded in the accompanying data set. Find a 99% confidence interval for u – µ2. Assume that the differences of the distances are approximately normally distributed. Figure 1: A picture of a gull.
