In a single-factor ANOVA problem involving five populations or treatments with a random sample of nine observations from each one, suppose that $H _ { o }$ is rejected at .05 level. Which of the following values are correct for the appropriate $Q _ { \alpha }$ critical value needed to perform Tukey's procedure?
A) 4.76
B) 3.79
C) 4.04
D) 3.85
E) 4.80

The correct critical value for Tukey's procedure can be found using the studentized range distribution table for $ \alpha = 0.05 $, $ k = 5 $ groups, and $ df = 40 $ (since $ n = 9 $ for each group, total $ N = 45 $, and $ df = N - k = 40 $). The closest value in the table is 4.04.
