Question 615922: Answer the following:
- If the correlation coefficient is -0.53, what is the sign of the slope of the regression line?
- As the correlation coefficient increases from 0.51 to 0.56, 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 -0.53, what is the sign of the slope of the regression line?
Answer: Since the correlation coefficient is negative, the slope of the regression line is negative

- As the correlation coefficient increases from 0.51 to 0.56, do the points of the scatter plot move toward the regression line, or away from it?
Answer: as the correlation coefficient increases to 1, the points will move closer to the regression line. Remember that a larger correlation coefficient (in absolute value) means a stronger correlation.
