Suppose that the lifetimes of tires of a certain brand are normally distributed with a mean of 74000 miles and a standard deviation of miles. These tires come with a -mile warranty. The manufacturer of the tires can adjust during the production process, but the adjustment of is quite costly. The manufacturer wants to set once and for all so that only of the tires will fail before warranty expires. Find the standard deviation to be set.
