You conduct a one-way ANOVA with 3 groups and find a statistically significant result using a = 0.05. Since it is significant, you follow this up with a post-hoc analysis. In particular, you plan to examine all pairwise contrasts. How many pairwise contrasts will you need to examine? If you used a = 0.05 for EACH comparison, what is the probability of making at least one Type I error? Recall that a Type I error is incorrectly rejecting the null hypothesis. (Round to three decimal places.)
