Question: A researcher conducts a randomized block experiment with interaction and provides the following ANOVA table.
a. At the 1 % significance level, can you conclude that there is interaction between the two factors?
b. Are you able to conduct tests based on the main effects? If yes, conduct these tests at the 1% significance level. If no, explain.
