WebBecause T 1, and T 2 are less than the quantile of the Student t-distribution, t 0.975 (4) = 2.7764, both tests lead to a conclusion that H 0: β 2 = 0, β 1 = 0.148 should be accepted. This conclusion is, however, false. The more rigorous approach uses a simultaneous test of the composite hypothesis H 0: β 2 = 0 and β 1 = 0.148.
