The F-test of the randomized block design of the analysis of variance requires that the random variable of interest must be normally distributed and the population variances must be equal.When the random variable is not normally distributed,we can use:
A) one-way ANOVA.
B) two-way ANOVA.
C) Friedman test.
D) all of these.

When the random variable is not normally distributed, the Friedman test can be used instead of the F-test of the randomized block design of the analysis of variance. One-way and two-way ANOVA both assume normality and equal variances, so they are not appropriate in this case. Therefore, the best choice is to use the Friedman test.
