Consider the study described in Problem 8. What is the 2-year cumulative incidence of hypertension?

Five hundred people are enrolled in a 10-year cohort study. At the start of the study, 50 have diagnosed CVD. Over the course of the study, 40 people who were free of CVD at baseline develop CVD.
• a. What is the cumulative incidence of CVD over 10 years?
• b. What is the prevalence of CVD at baseline?
• c. What is the prevalence of CVD at 10 years?
