Which of the following procedures is NOT robust to non-Normality?

Question

Quizplus · Accepted Answer

The F test for comparing two population standard deviations assumes Normality, so it is not robust to non-Normality. The other procedures (one-sample t test, t test for matched pairs, and two-sample t test) have robust alternatives (Wilcoxon-Mann-Whitney test, Wilcoxon signed-rank test, and permutation test, respectively) that can be used if Normality assumptions are violated.
