Answer:
B) 35.
Step-by-step explanation:
We know that a scatter plot is used to study to variables and see if they have some dependent relation, which is shown with a straight line. So, our job is to find the straight line that includes the major number of given points.
To have the best prediction possible, we draw a line that best fits to all points included in the scatter plot, as the image attached shows. There you can observe that the best prediction for 40 highway mpg is 35, because the red line shows that it must be between 30 and 40.
Therefore, the answer that best fits is B) 35.
