A used car dealer says that the mean price among all 2005 Honda Pilot LX's for sale in the United States is $23,900. You suspect this is wrong, and find that a simple random sample of 14 vehicles of this type has a mean price of $23,000 and a standard deviation of $1113. Do the data provide convincing statistical evidence (at the a=0.05 significance level) to believe the mean is different than the dealer says?
