Answer 1

The correct answer is A. There is a negative association because as the weight increases, the number of miles per gallon decreases.

The scatter plot shows a negative relationship between the weight of an SUV and its gas mileage. This means that as the weight of an SUV increases, its gas mileage decreases.

The correct answer is A. There is a negative association because as the weight increases, the number of miles per gallon decreases.

Here are some additional details about the scatter plot:

The points are generally clustered in the middle of the graph, with a few outliers at the top and bottom.

The trendline is sloped downward from left to right, which indicates a negative relationship.

The correlation coefficient for this data is -0.82, which is a strong negative correlation.
