Question

match each correlation coefficient to the appropriate scatter plot. the line in each scatter plot is the least squares regression line.
r = 1 r = -0.5

Explanation:

Step1: Analyze right scatter plot

All points lie exactly on an upward-sloping regression line, indicating a perfect positive linear relationship. A perfect positive correlation has a coefficient $r=1$.

Step2: Analyze left scatter plot

Points are scattered around a downward-sloping regression line, showing a moderate negative linear relationship. This matches the coefficient $r=-0.5$.

Answer:

• Left scatter plot: $r = -0.5$
• Right scatter plot: $r = 1$
