Figure 14.34 shows two scatterplots, each with the best-fitting line drawn through the points on the plot. Points represent cases in the data with particular values for the x and y variables. In each plot, the “x” represents the point on the best-fitting line when x equals 20.

a. Which scatterplot has larger residuals? How do you know?

b. How many negative residuals are there in scatterplot A? How many in scatterplot B? How do you know?

c. In each scatterplot, a single point in the plot is circled. Calculate the residual for each of the circled points in scatterplots A and B.
