12. Assume that Exhibit B.1 summarizes the 2015 population in the United States by race and gender. Exhibit B.2 presents the number of US residents in the four race/gender categories with each of five different risk factors. Use Exhibit B.3 as a template to calculate the prevalence rate (per 100) of these five risk factors among the four race/gender categories.
