b. Assume the following results: 2600 subjects were enrolled in the study. Of these subjects 220 who had diabetes also had a history of alcohol use. 60 subjects had diabetes but did not have a history of alcohol use. A total of 1080 subjects in the study had no history of alcohol use. Calculate the risk of having diabetes for subjects with a history of alcohol use compared with subjects without a history of alcohol use. [In other words, calculate either the odds ratio or relative risk, whichever is more appropriate, and interpret your result]. c. Calculate and interpret the 95% Confidence Interval for the risk estimate calculated above. d. Is the risk estimate calculated above statistically significant? Explain.

of having diabetes for subjects with a history of alcohol use compared with
subjects without a history of alcohol use. [In other words, calculate either the
odds ratio or relative risk, whichever is more appropriate, and interpret your
