match each correlation coefficient to the appropriate scatter plot. the line in each scatter plot is the least squares regression line.\nr = 0\nr = -0.7

match each correlation coefficient to the appropriate scatter plot. the line in each scatter plot is the least squares regression line.\nr = 0\nr = -0.7

Answer

Explanation:

Step1: Understand correlation coefficient meaning

The correlation coefficient $r$ measures the strength and direction of a linear relationship. $r = 0$ means no linear relationship, and $r=- 0.7$ means a strong negative - linear relationship.

Step2: Analyze scatter - plots

In the first scatter - plot, the points are randomly scattered around a horizontal line, indicating no linear relationship. In the second scatter - plot, the points generally follow a downward - sloping line, indicating a negative linear relationship.

Answer:

$r = 0$ matches the first scatter - plot; $r=-0.7$ matches the second scatter - plot.
