Scenario 5.4: Consider the following data on lung cancer and workers exposed to coal dust: Risk Factor Diseased Not Diseased Exposed 10 990 Non exposed 5 2995 Given that this was a retrospective study, answer the following questions. Calculate the 95% Cl for scenario 5.4 using the appropriate test in the form (LB, UB). Use 3 decimal points for all the steps of your calculations. Give your answers or LB and UB in the following 2 questions below rounding to exactly 3 decimal points in the form 6.123. Question 18 1.5 pts LB: Question 19 1.5 pts UB= Question 20 2 pts Fill in the blanks using options as shown on the parentheses. No blanks or any other symbols before or after your answers. Conclusion for scenario 5.4: As the 95% Cl (capture | does not capture) the Ho: OR=(give number) we (reject | fail to reject) the Ho and conclude that there (is | is no) an association between lung cancer disease and coal dust
