Question

(06.02 LC)

Answer 1

I would say line R because It is like in the middle of all the points. Not too many points are above or below the line
hope this helps:)

Answer 2

Answer:

The correct option is 3. Line R represents the line of best fit for this scatter plot.

Step-by-step explanation:

A straight line is called line of best fit if it minimize the sum of the squared prediction errors. It means the distance of all the points from the line is minimum.

The best fit line may or may not passes through the scatter points. Some scatter points lie above the line and some lie below the best fit line. In other words the best fit line passes through the middle points.

From the given graph it is clear that the line R passes through 3 points. The number of points above the line is equal to the number of points below the line. So, R is the line of best fit

Line R represents the line of best fit for this scatter plot. Therefore the correct option is 3.
