Calculate a regression equation using the explanatory variables suggested in Question 5 and Price as the response. Identify any residuals (or cluster of residuals) that don’t seem to fit the overall pattern in the residual versus fit and residual versus mileage plots. Any data values that don’t seem to fit the general pattern of the data set are called outliers.
a. Identify the specific rows of data that represent these points. Are there any consistencies that you can find?
b. Is this cluster of outliers helpful in identifying the patterns that were found in the ordered residual plots? Why or why not?
