Data were collected for 25 new cars on the cars’ weights (X) and estimated highway miles per gallon (Y). The model Y = α + βX + ε was estimated by least squares in three ways: the data were arranged alphabetically by car name, the data were arranged numerically from the lightest car to the heaviest, and the data were arranged numerically from the lowest miles per gallon to the highest. Which procedure yielded the smallest estimate of the intercept? Which yielded the highest estimate?
