... the final model. If β1= 0 then that is equivalent to saying that x is not in the model. So the variation in y is random and not dependent on x. The Hypothesis test H0: β1= 0 Vs HA: β1≠ 0 therefore tests whether the model is USEFUL. If we reject the Null hypothesis for this test then we conclude that ...
