Interpretation of the ANOVA table The test statistic is the \(F\) value of 9.59. Using an \(\alpha\) of 0.05, we have \(F_{0.05; \, 2, \, 12}\) = 3.89 (see the F distribution table in Chapter 1). Since the test statistic is much larger than the critical value, we reject the null hypothesis of equal population means and conclude that there is a (statistically) significant difference among the

If you run the regression without the 'robust' option you get the ANOVA table R2 shows the amount of observed variance explained by the model, in this case 94 %.
