Consider the following hypothetical scenario: The Idaho Kidney Center analyzed deaths among patients with
kidney disease who were seen at their program from 1/1/2006 through 12/31/2011. A total of 2,965 deaths
occurred during the observation period among the 22,735 study population. The table below gives the race and
gender of the decedents and the total population.
Characteristic Decedents (N = 2,965) Total Study Population (N = 22,735)

Using the scenario above, calculate and explain how to find the prevalence of Hispanics in the total study
population. Then, calculate and explain how to find the ratio of males to females in the total study population.
What is the proportion of Black, non-Hispanic decedents in this program? In addition, what is the proportion of
White, non-Hispanic decedents in this study? Explain why this information is necessary for an epidemiological
study
