Show answer & explanation
Correct answer: C
Non-parametric tests are distribution-free, meaning they do not require a specific population distribution (Statement C is true). They generally do not assume homogeneity of variance, which is a parametric assumption (Statement B is false). Random sampling is still required for valid inference (Statement D is false). These tests are often quicker and easier to apply than parametric alternatives when assumptions aren't met (Statement E is true). Therefore, the correct combination includes C and E.
