Suppose we want to study the effect of cigarette smoking on the incidence rate of primary open-angle glaucoma. The following data were obtained from the Nurses' Health Study (NHS) over the time period 1980-1996 and the Health Professionals' Follow-Up Study (a study of male health professionals) over the time period 1986-1996. Never Smokers Group Sex # Cases | Person-Years TO0IE Male |7 | im0 Current Smokers Group Person-Years e Fomale | 38 | 147476 | Male 10 17,706 Part a [f we assume the age distributions of current smokers and never smokers are comparable within each study, then test the hypothesis that current cigarette smoking is associated with the incidence of open-angle glaucoma. Report a two-tailed p-value and a conclusion in the context of the problem. Partb Test for the homogeneity of the incidence rate ratio between men and women. Report a p-value and a conclusion in the context of the problem.| Partc If appropriate, estimate the common incidence rate ratio relating current cigarette smoking to the incidence of open-angle glaucoma. Support your estimate with a 95% confidence interval. Write a sentence or two interpreting these results in the context of the
