Suppose researchers carry out a one-way ANOVA involving 3 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?

Important: Enter your answer as a percentage confidence level, but without the percent sign. For example, if your answer is 98.627%, enter 98.627.
