Chapter 0, Problem 13.81(choose chapter or problem)
The accompanying figure is from the article Root and Shoot Competition Intensity Along a Soil Depth Gradient (Ecology [1995]: 673682). It shows the relationship between above-ground biomass and soil depth within the experimental plots. The relationship is described by the linear equation: biomass 9.85 25.29(soil depth) and r 2 .65; P 0.001; n 55. Do you think the simple linear regression model is appropriate here? Explain. What would you expect to see in a plot of the standardized residuals versus x?
