Question

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

Answer 1

Answer:

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

Step-by-step 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.
