A study of the atmospheric pollution on the slopes opf the Blue Ridge Mountains was conducted. The levels of lead found in 70 fern moss specimens (y; in micorgrams of lead per gram of moss tissue) is collected from the mountain slopes, as well as the elevation of the moss specimen (x1; in feet) and the direction of the slope face (x2; 1 if east, 0 if west). A model is fit using the interaction term between elevation and direction of slope face to model levels of lead. Results from R are given below. Coefficients: Estimate Std.
