Which of the following statements is false?

C) Given sample size and specified significance level, the probability of a Type II erroris larger for a nonparametric test.
D) Using a nonparametric test when we could employ a parametric test can be less efficient: A nonparametric test often tends to ignore available sample information-for example, by focusing only on the directions rather than the sizes of observed differences.
E) None of these.
