A tennis racquet manufacturer designed a new racquet. They claim the new one will allow user to return more serves than any racquet currently sold. A group of male volunteers who currently play tennis and own their own racquets agree to participate in the study.
a) Design an experiment that would test the manufacturers claim.
b) Suppose the volunteer group had included both men and women. Would you adjust the design of your experiment? If so, provide the new design.
What are they looking for here????
