d. With SES as the exposure, which of the following groups has the highest risk of mortality? (Select or highlight one response.) a. High SES b. Medium SES C. Low SES e. Would the OR or the RR be more appropriate to describe the association between SES and mortality in this population? Why? Calculate the associations (i.e., the ORs or the RRs) and 95% Cls for the relationship between SES and mortality in this population. Assume low SES is the unexposed group. f.
