Question

A certain brand of automobile tire has a mean life span of 37,000 miles and a standard deviation of 2,450

miles.​ (Assume the life spans of the tires have a​ bell-shaped distribution.) Find the​ z-score that corresponds to each life span.

For the life span of 35,000 ​miles, z-score is....
​(Round to the nearest hundredth as​ needed.)
 
For the life span of 36,000 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?
