The wear resistances of two types of automobile tires were compared on road test samples of n1 = n2 = 100 tires for each type and the number of miles traveled to deterioration, defined as a specific amount of tire wear, was recorded. tire. The test results are shown in the table. Estimate (mu subscript 1 minus mu subscript 2), the difference in the mean miles to complete wear, using a 99% confidence interval. Is there a difference in the average wear quality for the two types of tires? summary of sample data for two types of tires rim 1: x1 = 26400 miles s1 ^ 2 = 1,440.00 Rim 2: x2 = 25,100 miles s2 ^ 2 = 1,960,000
