Question 415815: A. If the correlation coefficient is 0.04, what is the sign of the slope of the regression line?
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?

You can put this solution on YOUR website! 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
