The scatterplot below shows the model year, x, and the asking price, y, of cars of a particular model on a used car website. There is one car at the point 1989, 3475). Suppose the data set had been presented without this car included. What effect would this point's absence have on the correlation coefficient?
A) The correlation coefficient would increase.
B) the correlations coefficient would decrease.
C) It is impossible to determine the effect without recalculating the correlation coefficient.
D) The correlation coefficient would be unchanged since the form of the scatterplot is nonlinear.
E) The correlation coefficient would be unchanged since the point is consistent with the rest of the trend.
