Lcertain brand of automobile tire has a mean life span of 33,000 miles and a standard deviation of 2,200 miles. (Assume the life spans of the tires have a bellshaped distribution.) E) a) The life spans of three ra ndo ml):r selected tires are 35,000 miles, 31000 miles, and 32,000 miles. Find the zscore that corresponds to each life span. -'or the life span 0135.000 miles, zscore is 0.91 . Round to the nearest hundredth as needed.) "or the life span of 31000 miles, zscore is 1.82 . Round to the nearest hundredth as needed.) "or the life span of 32,000 miles, zscore is 0.45. Round to the nearest hundredth as needed.) tccording to the zscores, would the life spans of any ofthese tires be considered unusual? I)? No '3' Yes b) The lite spans of three randomly selected tires are 30,300 miles, 35,200 miles, and 33,000 miles. Using the empirical mle, find the percentile that corresponds to each life span. 'he life span 30,300 miles corresponds to a percentile of :l. "he life span 35,200 miles corresponds to a percentile of :l. "he life span 33,000 miles corresponds to a percentile of :|. Round to the nearest whole number as needed.)
