What conclusion regarding the null hypothesis should you make based on the given data?
An article published in USA Today stated that "in a study of 200 colorectal surgery patients, 104 were kept warm with blankets and intravenous fluids; 96 were kept cool. The results show: Only 6 of those warmed developed wound infections vs. 18 who were kept cool." Using a 0.05 significance level, you need to test the claim of the article's headline: "Warmer surgical patients recover better." This means that fewer of the warmer patients (group 1) developed infections as compares to cooler patients (group 2).
