We have to see which model (quadratic or linear) best represents the data.
We can use software to fit this data set.
Linear model:
Quadratic model:
The quadratic model has a slightly better fit than the linear model.
But the value of R² = 0.176 shows that the fit is very weak, so we can conclude that this is not a good model for the data.
Answer:
Quadratic model, 0.176.
No, 0.176 is a very low R² value.
