T A certain brand of automobile tire has a mean life span 38,000 miles and a standard deviation of 2,300 miles. (Assume the life spans of the tires have a bell-shaped distribution.) of According to the z-scores, would the life spans of any of these tires be considered unusual? Yes No (b) The life spans of three randomly selected tires are 35,700 miles, 40,300 miles, and 38,000 miles. Using the empirical rule, find the percentile that corresponds to each life span. The life span 35,700 miles corresponds to a percentile of The life span 40,300 miles corresponds to a percentile of The life span 38,000 miles corresponds to a percentile of (Round to the nearest whole number as needed.) 4 olo 2 40 3 38
