Question

match each correlation coefficient to the appropriate scatter plot. the line in each scatter plot is the least squares regression line.
r = 0
r = 0.8

Explanation:

Step1: Analyze left scatter plot

The points cluster closely around an upward-sloping regression line, showing a strong positive linear relationship. This matches $r=0.8$, as $r$ close to 1 indicates strong positive correlation.

Step2: Analyze right scatter plot

The points are randomly scattered around a horizontal regression line, showing no linear relationship. This matches $r=0$, as $r=0$ means no linear correlation.

Answer:

Left scatter plot: $r=0.8$
Right scatter plot: $r=0$
