A particular brand of tires claims that its deluxe tire averages
at least 50,000 miles before it needs to be replaced. From past
studies of this tire, the standard deviation is known to be 8,000.
A survey of owners of that tire design is conducted. Of the 32
tires surveyed, the mean lifespan was 46,600 miles with a standard
deviation of 9,800 miles. Using alpha = 0.05, is the data highly
consistent with the claim?
