Exercises 8.83 and 10.73 presented some data collected in a 1993 study by Susan Beckham and her colleagues. In this study, measurements of anterior compartment pressure (in millimeters of mercury) were taken for ten healthy runners and ten healthy cyclists. The researchers also obtained pressure measurements for the runners and cyclists at maximal O2 consumption. The data summary is given in the accompanying table.Runners Cyclists Condition Mean s Mean s Rest 14.5 3.92 11.1 3.98 80% maximal O2 12.2 3.49 11.5 4.95 consumption Maximal O2 consumption 19.1 16.9 12.2 4.67 a Is there sufficient evidence to support a claim that the variability of compartment pressure differs for runners and cyclists who are resting?
