The Wilcoxon signed-rank test uses T values and the Mann-Whitney U test uses U values, and in both cases, the observed value is considered statistically significant if it is equal to or less than the critical value. Therefore, option D, which includes both A and B, is the correct answer. The Spearman rank-order correlation uses r values, but statistical significance is determined by comparing the computed p-value to the chosen significance level (usually 0.05), not by comparing the observed value to a critical value.
