For questions 13-18, refer to the following information: 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, while 96 were kept cool. The results indicate that only 6 of those warmed developed wound infections compared to 18 who were kept cool.\" Using a 0.05 signicance level, 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 compared to cooler patients (group 2). To test the hypothesis, you'll need to answer the following questions. 13. What proportion of cooled patients developed wound infections? (0.5 point) a. 0.06 b. 0.09 c. 0.12 d. 0.19 e. 0.96 14. What is the null hypothesis (Ho)? (1 point) a-P1 = P2 l9-P1 3* P2 (3- P1 2 P2 d-P1
