Discuss the effect that the observation (20, 33,000) will have on the estimated regression line. If this point were omitted, what can you say about the slope of the estimated regression line? What do you think will g1x x2 g1x x2 1y y2 2 x y g xy g y2 g y g x2 g x happen to the slope if this observation is included in the computations?
