Atire company has developed a new type of steel-belted radial tire. extensive testing indicates the population of mileages obtained by all tires of this new type is normally distributed with a mean of 40,000 miles and a standard deviation of 4,000 miles. the company wishes to offer a guarantee providing a discount on a new set of tires if the original tires purchased qualify the guarantee mileage. what should the guaranteed mileage be if the tire company desires that no more than 2 percent of the tires will fail to meet the guaranteed mileage?
