Answer true or false to the following statements and explain your answers.

a. If the conditions for a randomized block ANOVA are met, then it is valid to use (i.e., the assumptions are satisfied for using) the Friedman test for testing the hypothesis of no treatment effect.

b. If the assumptions for a Friedman test are satisfied and the distributions of the response variable for the treatment-block combinations are skewed, then the randomized block ANOVA F-test is usually less powerful than the Friedman test for testing the hypothesis of no treatment effect.
