Solution Steps

Step 1: Identify the Variables

The scatterplot shows the relationship between the weight of cars (in hundreds of pounds) on the horizontal axis and their miles per gallon (mpg) on the vertical axis.

Step 2: Determine the Overall Direction of the Data

Observe the trend in the scatterplot. As the weight of the cars increases, the miles per gallon generally decreases. This indicates a negative correlation.

Step 3: Assess the Strength of the Association

Evaluate how closely the data points follow the trend. The points are fairly close to a downward-sloping line, suggesting a strong negative association.

Final Answer

The overall direction of this data is negative. The strength of the association is strong.
