Three tennis players, a beginner, an intermediate, and advanced, have been randomly selected from the membership of a racquet facility club in a large city. Using the same tennis ball, each player hits ten serves, one with each of three racquet models, with the three racquet models selected randomly. The speed of each serve is measured with a machine and the result recorded. Among the ANOVA models listed below, the most likely model to fit this situation is the:
a. one-way ANOVA.
b. two-way ANOVA.
c. randomized block design.
d. none of these.

Question 2

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.
