A particular brand of tires claims that its deluxe tire averages at least 50,000 miles before it needs to be replaced. A survey of owners of that tire design is conducted. From the 28 tires surveyed, the mean lifespan was 46,500 miles with a standard deviation of 9,800 miles. If we assume the underlying data is normally distributed, does this suggest the mileage claim is too high?
