Create a residual versus order plot from the TPrice versus Mileage regression line. Describe any pattern you see in the ordered residual plot. Apparently something in our data is affecting the residuals based on the order of the data. Clearly, time is not the influential factor in our data set (all of the data are from 2005). Can you suggest a variable in the Cars data set that may be causing this pattern?
