Question

A residual plot is shown.

Which statements are true about the residual plot and the equation for the line of best fit for the data? Check all that apply.

1) The equation for the line of best fit is not a good approximation for the data because the points have a curved pattern.

2) The equation for the line of best fit is a good approximation for the data because the points are random, having no pattern.

3) The residual plot has a linear pattern.

4) The points of the residual plot are spread evenly above and below the x-axis.

5) The residual plot has the pattern of a curve.

6) The equation for the line of best fit is not a good approximation for the data because the points have a linear pattern.

Answer 1

1 and 5

Explanation:

Answer 2

The only answers you can really use is the first and fifth ones.

The second one is not true because the point do not look random. they look like they might be a parabola

The third one is not a choice because plot does not have a linear (straight line) pattern. Linear means straight line.

The fourth one is not true. There is only 1 point below the x axis. The rest are above the x axis.

The 5th one is true.

The 6th one is not true. Those points do not have a straight line pattern.
