Eight amateur boxers participated in an experiment to investigate the effect of massage on boxing performance (British Journal of Sports Medicine, Apr. 2000). The punching power of each boxer (measured in new tons) was recorded in the round following each of four different interventions: (M1) in round 1, following a pre-bout sports massage; (R1) in round 1, following a pre-bout period of rest; (M5) in round 5, following a sports massage between rounds; and (R5) in round 5, following a period of rest between rounds. Based on information provided in the article, the data in the accompanying table were obtained and saved in the BOXING file. The main goal of the experiment was to compare the punching power means of the four interventions.

a. Set up H0 and Ha for this analysis.
b. Identify the treatments and blocks in the experiment.
c. Conduct the test set up in part a. What conclusions can you draw regarding the effect of massage on punching power?
