One of the results in the Original Source was “there were only two symptoms that men experienced more often than women: vomiting (men: 50%; women: 44%; chi-square statistic = 4.7, p = 0.031) and sweating more than usual (men: 34%; women: 23%; chi-square statistic = 18.9, p, < 0.001)” (Slutske, Piasecki, and Hunt­Carter, 2003, p. 1446). State the null and alternative hypotheses for each of these two results.
