Question description

   A used car dealer says that the mean price of a 2005 Honda Pilot LX is at least $23,900. You suspect this claim is incorrect and find that a random sample of 25 similar vehicles has a mean price of $23,000 and a standard deviation of $1100. Is there enough evidence to reject the dealer’s claim at alpha = .05? Use the t-test.
