You conduct a 1-way ANOVA with 7 groups and find a statistically significant result (using a = 0.02). 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. How many pairwise contrasts will you need to examine? What is the probability of making at least one Type I error (Familywise Error Rate)?
