Question

You are a consumer advocate. A particular brand of tires state that they last for 50,000 miles before it needs to be replaced. You solicit survey responses from people that own the tire to ask how many miles their tire lasted before they had to replace them. The survey results showed an average life-span of 46,500 miles with a standard deviation of 9,800 miles. Which statistical test would be best to determine if the tires last significantly less than 50,000 miles?
