A used car dealer says that the mean price of a three-year-old sports utility vehicle is $19,000. You suspect this claim is incorrect and find that a random sample
of 25 similar vehicles has a mean price of $19,739 and a standard deviation of $1916. Is there enough evidence to reject the claim at a = 0.01? Complete parts
