Lifetime of a tire Assume the random variable L in Example 2f is normally distributed with mean u = 22,000 miles and o = 4,000 miles. a. In a batch of 4000 tires, how many can be expected to last for at least 18,000 miles? b. What is the minimum number of miles you would expect to find as the lifetime for 90% of the tires?
