A used car dealer says that the mean price of aβ three-year-old sports utility vehicle is β$22,000. You suspect this claim is incorrect and find that a random sample of 25 similar vehicles has a mean price of β$22,549 and a standard deviation of β$1995. Is there enough evidence to reject the claim at Ξ±=0.05β?
