Consider again the one-way ANOVA hypothesis test described in Problem 29. Suppose now that the professional golf association wants to compare the mean distances traveled by four brands of golf balls using human golfers instead of a robotic golfer. Each human golfer who participates in the experiment will employ the same type of driver to hit a subset of the 80 balls.
a. Explain how a randomized experimental design could be used to perform this one-way ANOVA.
b. Explain how a randomized block design could be used to perform this one-way ANOVA.
