If the correlation coefficient is 0.54, what is the sign of the slope of the regression line?
 As the correlation coefficient decreases from 0.86 to 0.81, do the points of the scatter plot move toward the regression line, or away from it

It goes from upper left to lower right, so what would the sign be?
There is more variability as the correlation coefficient decreases, so away.
