Does Massage Help Heal Muscles Strained by Exercise? After exercise, massage is often used to relieve pain, and a recent study showed it may reduce inflammation and help muscles heal. The study found that massage therapy reduced inflammation by 10 minutes on one quadricep and no treatment on the other, with treatment randomly assigned. After 2.5 hours, muscle biopsies were taken to provide a quantification of the inflammatory cytokine interleukin-6 was measured relative to the resting level. The differences (control minus massage) are given in Table 1 below.

What is the sample mean difference in inflammation between no massage and massage? State the null and alternative hypotheses. Use instead of D to answer this question. Use StatKey or other technology to find the p-value from a randomization distribution. Round your answer to three decimal places. Are the results significant at a 5% level? State the conclusion of the test if we assume a 5% significance level (as the authors of the study did)
