According to the National Automobile Dealers Association, the mean price for used  cars is $9000. The manager of a Kansas City dealership reviewed a sample of sales at the dealership to determine whether the population mean price at this particular dealership differed from the national mean. The prices for the sample of  cars are shown in the file named Used Cars.
