In Exercise 8.83, we presented some data collected in a study by Susan Beckham and her colleagues. In this study, measurements were made of anterior compartment pressure (in millimeters of mercury) for ten healthy runners and ten healthy cyclists. The data summary is repeated here for your convenience. 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 a Is there sufficient evidence to justify claiming that a difference exists in mean compartment pressures for runners and cyclists who are resting? Use = .05. Bound or determine the associated p-value. b Does sufficient evidence exist to permit us to identify a difference in mean compartment pressures for runners and cyclists at 80% maximal O2 consumption? Use = .05. Bound or determine the associated p-value.
