To find the critical value for the Tukey test statistic, we need to consult a Tukey Table with degrees of freedom (df1 = k − 1, where k is the number of groups or treatments) and df2 = N - k, and α = 0.05. In this case, k = 4 and N = 24, so df1 = 3 and df2 = 20.

Looking up in the Tukey table for df1 = 3, df2 = 20, and α = .05, the critical value is 2.80. Therefore, the answer is B.
