Explanation / Answer
P_value is the evidence against the null hypothesis. Smaller the P-cvalue stronger the evidence against null hypothesis. If P-value is lesser than the significance level 0.05 then we will reject the ull hypothesis. In the given ANOVA summary p-value of Factor A and Factor B is less than 0.05 . And P-value of Interaction between A and B is less than 0.05 .therefore we conclude that there is a significant interaction between Factors A and B.
