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:

1. For the right scatter plot: All points lie perfectly on a downward-sloping regression line, which indicates a perfect negative linear correlation. A perfect negative correlation corresponds to a correlation coefficient of $r=-1$.
2. For the left scatter plot: Points show a general upward trend but are not tightly clustered around the regression line, meaning a moderate positive linear correlation. This matches the correlation coefficient $r=0.5$.

Answer:

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