WebCalculate the ANOVA table with degrees of freedom (df) and F value as shown below. Determine the critical value. Remember, F(critical) is from the F distribution table. Finally, Draw the statistical conclusion. If Fcalc< Fcritica,l fail to reject the null hypothesis, and if Fcalc > Fcritical, reject the null hypothesis. WebInterpretation 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 …
