Question

Find the residual values, and use the graphing calculator tool to make a residual plot.

a.No, the points are in a curved pattern.
b.No, the points are evenly distributed about the x-axis.
c.Yes, the points are in a linear pattern.
d.Yes, the points have no pattern.

Answer 1

A.

Explanation:

Answer 2

a. No, the points are in a curved pattern.

Explanation:

The residual values are basically the difference between Given values and Predicted values.

So, the complete table would be

x Given Predicted Residual

1 -2.7 -2.84 0.14

2 -0.9 -0.81 -0.09

3 1.1 1.22 -0.12

4 3.2 3.25 -0.05

5 5.4 5.28 0.12

Now, to make a residual plot, we just need to graph all points formed by x-colum and residual column.

The image attached shows the residual plot.

Therefore, the right answer is a., because in the residual plot you can notice that the points are in a curved pattern, like in a parabola-like pattern.
