Question 227165: If the correlation coefficient is 0.91, what is the sign of the slope of the regression line?
- As the correlation coefficient decreases from -0.21 to -0.27, do the points of the scatter plot move toward the regression line, or away from it?

You can put this solution on YOUR website! If the correlation coefficient is 0.91, what is the sign of the slope of the regression line?
Ans: positive

- As the correlation coefficient decreases from -0.21 to -0.27, do the points of the scatter plot move toward the regression line, or away from it?
Ans: Toward
The -0.27 is closer to -1 and indicates a stronger negative linear
correlation than -0.21
