Question

The manufacturer of the X-15 steel-belted radial truck tire claims that the mean mileage the tire can be driven before the tread wears out is 60,000 miles. The population standard deviation of the mileage is 5000 miles. Crosset Truck Company bought 48 tires and found from this purchase of tires that the average mileage for its trucks is in fact 58,500 miles.

Use critical value approach and p-value approach to undertake your hypothesis testing. Your test is to know whether the Crosset’s experience is different from what is claimed by the manufacturer at a 5% significance level.
