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.
