If we find that the null hypothesis, HO: Bj=0, cannot be rejected

If we find that the null hypothesis, HO: Bj=0, cannot be rejected when testing the contribution of an individual regressor variable to the model, we usually should: O remove the variable from the model. O do nothing. O add a quadratic term in x; to the model. Odo none of the above.
