The accompanying scatterplot, based on 34 sediment samples with x 5 sediment depth (cm) and y 5 oil and grease content (mg/kg), appeared in the article

“Mined Land Reclamation Using Polluted Urban Navigable Waterway Sediments” (Journal of Environmental Quality [1984]: 415–422). 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 happen to the slope if this observation is included in the computations?
