show work 1. A study was conducted to investigate the effectiveness of hypnotism in reducing pain. Results forrandomly selected subjects are shown in the table below. A lower score indicates less pain. The "before"value is matched to an "after" value and differences are calculated (after minus before; I ask you to com-plete the table by computing these differences). Assume the population of differences is approximatelynormal. Are the sensory measurements, on average, lower after hypnotism?
