WebThe test statistic is t = b 0 /se ( b 0) = 576.68/23.47 = 24.57, the value under T-Value. The p -value for the test is p = 0.000 and is given under P-Value. The p -value is actually very small and not exactly 0. The decision rule at the 0.05 significance level is to reject the null hypothesis since our p < 0.05. WebThe t test can be thought of as a simple regression model with the covariate taking on only two values, and the ANOVA can also be viewed as a regression model with multiple covariates.
