Test: Unit 2 Test Question 16 This Test: 18 pts possible Resume later Submit Test A certain brand of automobile tire has a mean life span of 35,000 miles and a standard deviation of 2,250 miles. (Assume the life spans of the tires have a bell-shaped distribution.) (a) The life spans of three randomly selected tires are 33,000 miles, 38,000 miles, and 32,000 miles. Find the z-score that corresponds to each life span. For the life span of 33,000 miles, z-score is (Round to the nearest hundredth as needed.) For the life span of 38,000 miles, z-score is (Round to the nearest hundredth as needed.) For the life span of 32,000 miles, z-score is (Round to the nearest hundredth as needed.) According to the z-scores, would the life spans of any of these tires be considered unusual? O Yes O No (b) The life spans of three randomly selected tires are 32,750 miles, 37,250 miles, and 35,000 miles. Using the empirical rule, find the percentile that corresponds to each life span. The life span 32,750 miles corresponds to the th percentile. The life span 37,250 miles corresponds to the th percentile. The life span 35,000 miles corresponds to the th percentile.
