Question

the scatter plot shows the weight and fuel efficiency for each of 25 vehicles. also shown is the line of best fit for the data. fill in the blanks below. (a) for these 25 vehicles, as weight increases, fuel efficiency tends to select (b) for these 25 vehicles, there is select correlation between weight and fuel efficiency. (c) using the line of best fit, we would predict that a vehicle weighing 3500 pounds would have a fuel efficiency of approximately select

Explanation:

Step1: Analyze scatter - plot trend

As we move from left to right (weight increases) on the x - axis, the points on the scatter - plot and the line of best fit move downwards on the y - axis (fuel efficiency decreases).

Step2: Determine correlation type

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

Step3: Estimate fuel efficiency

Locate 3500 on the x - axis (weight). Then, find the corresponding y - value (fuel efficiency) on the line of best fit. It appears to be around 25 miles per gallon.

Answer:

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