NotVaccmated Did Not Die Total b. Calculate the cumulative incidence (CI), also called the risk, of mortality separately for the vaccinated and unvaccinated groups. This means you will have 2 risk calculations. Show your work. Cl: risk of mortality (vaccinated) = CI = risk of mortality (unvaccinated) = c. Calculate and interpret (in a sentence) the mortality risk difference comparing vaccinated to unvaccinated people. Show your work. Risk Difference (RD) for mortality comparing vaccinated to unvaccinated = Interpret: d. Calculate and interpret (in a sentence) the mortality risk ratio comparing vaccinated to unvaccinated people. Show your work. Risk Ratio (RR) for mortality comparing vaccinated to unvaccinated = Interpret: e. Which measure would you use (Risk Difference=RD or Risk Ratio=RR) if you were asked to speak to the media to convey your public health message? Why
