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 with weight increase

Observe the scatter plot and line of best fit: as x (weight) increases, y (fuel efficiency) moves downward.

Step2: Identify correlation type

Since fuel efficiency decreases as weight increases, this is a negative correlation.

Step3: Predict value at 3000 lbs

Locate 3000 on the x-axis, move up to the line of best fit, then left to the y-axis. The corresponding value is 25.

Answer:

(a) decrease
(b) negative
(c) 25 miles per gallon
