Question: 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;

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). To do so, answer each of the following questions.

What is the p-value (corresponding to your test statistic of -2.82)?

a. 0.0012

b. 0.0024

c. 0.0048

d. 0.0500

e. 0.1000
