Question 415815
A. If the correlation coefficient is 0.04, what is the sign of the slope of the regression line?
Ans: positive
---------------------------- 
B. As the correlation coefficient increases from 0.22 to 0.20, do the points of the scatter plot move toward the regression line, or away from it?
Ans: That is not an increase.
r = 0.22 has less scatter than r = 0.20
