Question

When a student uses quadratic regression on a graphing calculator to model​ data, the value of is 0.2. Make a conjecture about the fit of the model.
Choose the correct answer below.
A.
The value of is close to​ 0, so the function models the data closely. The data are most likely quadratic.
B.
The value of is not close to​ 1, so the function does not model the data closely. The data are most likely quadratic.
C.
The value of is close to​ 1, so the function models the data closely. The data are most likely quadratic.
D.
The value of is not close to​ 1, so the function does not model the data closely. The data may not be quadratic.
