Suppose researchers carry out a one-way ANOVA involving 5 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 80%. 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. (Give your response to at least 3 decimal places.

We have developed a new drug used to reduce fever and want to test its efficacy. Ten ER patients who are running a fever agree to take the new drug instead of the traditional treatment. Their temperatures are taken before the drug is administered and 30 minutes after taking the drug. The results are recorded in the Excel file below. Use the data to construct and interpret a 99% confidence interval for the mean change in temperatures of patients after taking this drug using Excel. Be sure to include any explanation necessary along with a sentence that explains what the interval means.
