You conduct a 1-way ANOVA with 5 groups and find a statistically significant result (using α=0.05α=0.05). You intend to follow this up with a post-hoc analysis. In particular, you plan to examine all pairwise contrasts. You retain the same nominal significance level for all tests. Round your answers to three decimal places, if necessary.
