It has been shown that levels of beta-endorphin in the blood are elevated by emotional stress. For 19 patients scheduled to undergo surgery, blood samples were taken twice: (a) 12-14 hours before surgery and (b) 10 minutes before surgery. Beta-endorphin levels were measured in fmol/ml. Assuming the symmetry of the distributions, determine if there is a significant increase in beta-endorphin levels immediately before surgery.
