Assume you have four groups to compare through hypothesis tests and confidence intervals, and you want the overall level of significance to be 0.05.
a. How many possible comparisons are there?
b. What is the Bonferroni-corrected value of the significance level for each comparison?
c. What is the Bonferroni-corrected confidence level for each interval assuming an overall significance level of 0.05? Report the percentage rounded to two decimal digits, and show your calculations.
