7.    If you reject the null hypothesis in ANOVA, then what do you do?

8.    Assume we do a One-way ANOVA, and the overall ANOVA is significant. Further assume that the single treatment / factor has four levels. How many hypotheses tests are there?

9.    In a two-way ANOVA, with treatments paint and location, and with three levels. What are the three main hypothesis tests to tell whether the overall ANOVA is significant?
