Does stretching before exercise reduce the chance of injury? To answer this question, a random sample of 800 athletes was selected and split into two groups based on stretching preference. Of the 450 who do not stretch prior to exercise, 231 suffered an injury during the previous year. Of the 350 who stretch prior to exercise, 55 suffered an injury during the previous year. Is there enough evidence to conclude that stretching prior to exercise reduces the chance of injury based on these data? Find and interpret the p-value.
