Exercise 7

Suppose that "X" represents the name of a disease. An epidemiologist conducts a survey of disease "X" in a population. The prevalence of disease "X" among women is 40/1,000 and among men is 20/1,000. Assuming that the data have been age adjusted, is it correct to conclude that women have twice the risk of disease "X" as men? Explain.
