1. Considering each boxplot and sample size in turn, state any necessary assumptions on the distribution of the underlying population, and whether or not you're concerned about the assumption/s.

2. The ANOVA method requires the populations to have equal variance. Comment on the appropriateness of this assumption using the boxplots as evidence.

3. Based on the boxplots, what conclusion would expect to make in the ANOVA, and why? Would you expect the p-value to be larger or smaller than 5%?
