WebThe formal F -test for the slope parameter β 1 The null hypothesis is H 0: β 1 = 0. The alternative hypothesis is H A: β 1 ≠ 0. The test statistic is F ∗ = M S R M S E. As always, the P -value is obtained by answering the question: "What is the probability that we’d get an F* statistic as large as we did if the null hypothesis is true?" WebMar 30, 2024 · To determine critical values, you need to know the distribution of your test statistic under the assumption that the null hypothesis holds. Critical values are then the points on the distribution which have the same probability as your test statistic, equal to the significance level \alpha α. hungama apk download
