60 Effect of massage on boxers. The British Journal of Sports Medicine (Apr. 2000) performed a study of the effect of massage on boxing performance. Two other variables measured on the boxers were blood lactate concentration (in mM) and the boxer’s perceived recovery (on a 28-point scale). On the basis of information provided in the article, the data shown in the accompanying table (and saved in the BOXING2 file) were obtained for 16 five-round boxing performances in which a massage was given to the boxer between rounds. Conduct a test to determine whether blood lactate level ( y ) is linearly related to perceived recovery

( x ). Use a = .10.
