Question

the scatter plot shows the weight and fuel efficiency for each of 24 vehicles. also shown is the line of best fit for the data.
fill in the blanks below.
(a) for these 24 vehicles, as weight increases, fuel efficiency tends to select
(b) for these 24 vehicles, there is select correlation between weight and fuel efficiency.
(c) using the line of best fit, we would predict that a vehicle weighing 3000 pounds would have a fuel efficiency of approximately select

Explanation:

Step1: Analyze trend direction

Observe the scatter plot: as x (weight) increases, y (fuel efficiency) moves downward.

Step2: Identify correlation type

The downward trend means an inverse, negative relationship.

Step3: Predict value from best fit

Locate 3000 pounds on x-axis, move up to the line of best fit, then left to y-axis: the value is 30 mpg.

Answer:

(a) decrease
(b) negative
(c) 30 miles per gallon
