The manufacturer of a truck tire claims that the mean mileage the tire can be driven before the tread wears out is 60000 miles. The population standard deviation is 400 miles. A truck company bought 80 tires and found that the mean mileage for its truck is 59500 miles. Is the truck company’s experience different from the claim of the manufacturer at 5% level of significance? Is it one-tailed or two-tailed test? Also,compute p-value and interpret.
