How do I use the steepness calibrator to get the correlation coefficient?

3. Estimate the correlation coefficient between shoe size and the number of shoes in the scatter plot below. Hint: Compare the slope of the regression line to the SD line by drawing a triangular "steepness calibrator" as was done for you in the previous scatter plot. Start by drawing a horizontal line through point of averages (where the SD and regression line cross). The horizontal line has a slope of 0.
