Question

fuel efficiency (in miles per gallon) weight (in pounds) (a) for these 24 vehicles, as weight increases, fuel efficiency tends to select (b) for these 24 vehicles, there is select correlation between (c) using the line of best fit, we would predict that a vehicle weighing approximately select would have a fuel efficiency of

Explanation:

Step1: Analyze the graph trend

As the weight (x - axis) increases, the fuel - efficiency (y - axis) values are going down.

Step2: Determine the correlation type

Since an increase in weight leads to a decrease in fuel - efficiency, there is a negative correlation.

Step3: Predict using the line of best fit

The line of best fit shows a decreasing trend, so as weight increases, fuel - efficiency decreases.

Answer:

(a) decrease
(b) negative
(c) decrease
