Suppose that you have a bivariate data set and the correlation coefficient for the relationship betweenxandyis strong. Suppose also that you compute a least-squares regression line that seems to fit the linear pattern in this bivariate data. You decide to plot the observedx-values (along thex-axis)against the residuals (along they-axis).If the pattern in the data is truly linear, you should find that the residuals:
A.follow a u-shaped pattern.B.are randomly distributed around the liney-= 0.C.follow a linear pattern.D.are clumped at values above the liney-= 0.E. All of the above
