Let's look at probability in terms of both the real world and the medical community. 1. Survey 30 people to find out if they are left-handed or right-handed, and use the following chart to create a contingency table with the information. Left handed Right handed Total Female Male Total 2. Answer the following questions about the information in your contingency table: a. If a person is randomly selected from the survey participants, what is the probability that the person will be left-handed? b. If you randomly choose a female from the people you surveyed, what is the probability that she is left-handed? c. What is the odds ratio of choosing a left-handed female? d. What is the relative risk of choosing a left-handed female? Example Green Blue Total 20 (B) 60 (A+B) Cats 40 (A) 40 (D) 70 (C+D) Dogs 30 (C) Total 70 (A+C) 60 (B+D) 130 (A+B+C+D) a. Probability of Green - (A+C)/(A+B+C+D): 70/130 = 0.54 b. Probability of Green Cat - A/(A+B): 40/60 = 0.67 c. Odds Ratio of Green Cat - (A/B)/(C/D) or AD/BC: (4040)/(2030) = 1600/600 = 2.67 d. Relative Risk of Green Cat - [A/(A+C)]/[B/(B+D)]: (40/70)/(20/60) = 1.71 3. Skim through at least one of the following articles on left-handed vs. right-handed people from the Chamberlain Library. Answer the following question: How do the probabilities and percentages for your study compare to those in the study you read? a. https://search-proquest-com.chamberlainuniversity.idm.oclc.org/nahs/docview/211689160/DB2AB8D1E63B4638PQ/4?accountid=147674 b. https://search-proquest-com.chamberlainuniversity.idm.oclc.org/nahs/docview/1326739712/DB2AB8D1E63B4638PQ /10?accountid=147674
