A taxi company purchase Brand A and Brand B tires for its taxis fleet. To estimate the difference between the two brands of tire's life, an experiment was conducted using 12 taxis for each brand. The tires were run until they wear out and the distances (in kilometers) were measured. The descriptive statistics for the two brands of tires are shown below. Brand Population mean Population standard deviation A 36300 kilometers 5000 kilometers B 38100 kilometers 6100 kilometers Find the probability that the mean distance of tires to wear out for Brand B exceeds Brand A by more than 1000 kilometers.
