Chronic anterior compartment syndrome is a condition characterized by exercise-induced pain in the lower leg. Swelling and impaired nerve and muscle function also accompany the pain, which is relieved by rest. Susan Beckham and her colleagues14 conducted an experiment involving ten healthy runners and ten healthy cyclists to determine if pressure measurements within the anterior muscle compartment differ between runners and cyclists. The datacompartment pressure, in millimeters of mercuryare summarized in the following table: Runners Cyclists Condition Mean s Mean s Rest 14.5 3.92 11.1 3.98 80% maximal O2 consumption 12.2 3.49 11.5 4.95 a Construct a 95% confidence interval for the difference in mean compartment pressures between runners and cyclists under the resting condition. b Construct a 90% confidence interval for the difference in mean compartment pressures between runners and cyclists who exercise at 80% of maximal oxygen (O2) consumption. c Consider the intervals constructed in parts (a) and (b). How would you interpret the results that you obtained?
