Part 2:

Given that the correlation coefficient $r$ is approximately $-0.957$, this indicates:

• a strong negative linear association between the two variables.

Part 3:

The given graph should be:

• consistent with the interpretation found in part b, because the y-values appear to decrease as the x-values increase, and the data points appear clustered closely about the regression line.

This description aligns with the strong negative linear association found in the data.
