A certain brand of automobile tire has a mean life span of 37,000 miles and a standard deviation of 2,400 (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 33,000miles, z-score is [ ] (Round to the nearest hundredth as needed.) For the life span of 38,000miles, z-score is [ ] (Round to the nearest hundredth as needed.) For the life span of 32,000miles, z-score is [ ] (Round to the nearest hundredth as needed.)
