You have conducted a randomized controlled trial (RCT) to test the effect of a lunch program on middle school dropout rates. You recruited 800 high school elementary school pupils to participate in the study. 400 participants were randomized to receive information about existing lunch programs at their school, and the other 400 participants were randomized to receive existing information as well as participate in an after-school lunch program. At the end of the study, you find that 97 students in your "existing information" were dropouts, and 64 students in your "existing information+ after-school lunch group were dropouts. No students were lost to follow-up. Show working for all calculations A) calculative the cumulative incidence ratio for this study B) Use the below formula to answer the following. For each question, present final answers in decimal form to the nearest hundredth (ex. 0.00) In CIL,U = In RR 1.96 ln RR1.96 1 1 + A1 Ao | I. What is the 95% Confidence Interval lower bound. II. III. What is the 95% Confidence Interval upper bound. Provide the interpretation C) Given the answers to the A) and B) do you think you have provided strong evidence that the lunch programs prevent dropouts? D) Calculate and interpret the attributable proportion in the exposed for this study and use this result to support your answer in C).
