The manufacturer of the Blaze Motorcycle Tires claims that the mean mileage the tire can be driven before it wears out is 30,000 kms. Assume the mileage follows a normal distribution and the standard deviation of the distribution is 25,000 kms. Moga Home Delivery Company purchased 60 tires for its motorcycles and found that the mean mileage was 29,800 kms. Is this experience different from that claimed by the manufacturer at the .05 significance level?
