QUESTION 2 Children exposed to second-hand smoking often have a higher rate of asthma than those who are not. A hypothetical situation is presented in the following table showing the rates of disease in a hypothetical population. Use this information to answer the questions. Asthma No Asthma Total Smoking 1250 9875 11125 No Smoking 755 10255 11010 Total 2005 20130 N=22135 1) What is the cumulative incidence of disease in the exposed, per 1000 of the population? (Round to 2 decimal places) 2) What is the relative risk based on the table above? (Round answer to 2 decimal places)
