WebThe t-statistics and p-values are for the Null Hypothesis that each coefficient is equal to zero. Such a null hypothesis is appropriate for the cross-product terms which estimate curvilinear blending. WebMar 10, 2024 · 3. Use a t-distribution table to find the associated p-value. Once you've calculated the value of the test statistic "t," you can find the associated p-value by referring to a t-distribution table, which you can find on the internet. There are three major significance values on a t-distribution table that p-value uses: 0.01, 0.05 and 0.1. WebThe P -value is determined by comparing F* to an F distribution with 1 numerator degree of freedom and n -2 denominator degrees of freedom. In reality, we are going to let Minitab calculate the F* statistic and the P -value for us. Let's try it out on a new example!

WebThe p-value is a measure of the strength of the evidence in your data against H 0. Usually, the smaller the p-value, the stronger the sample evidence is for rejecting H 0. More specifically, the p-value is the smallest value of α that results in the rejection of H 0. WebMay 27, 2024 · The RJ test statistic then needs to be compared to that critical value: If RJ < CV, then the determination is NOT NORMAL. If RJ > CV, then the determination is NORMAL.
