Suppose researchers carry out a one-way ANOVA involving 4 groups. After finding statistically significant evidence of a difference in the group means, they decide to use the Bonferroni correction to come up with simultaneous confidence intervals for the pairwise differences, keeping the family-wise confidence level at least 85%. Help the researchers out here. Using the Bonferroni approach, what should the confidence level be for the individual intervals?
