1. Suppose that a 2012 report lists 100 heart attacks, 75 among men in a population of 25,000 men and 25,000 women. What is the ratio of heart attacks (men to women), the proportion of the heart attack report who are men, and the heart attack rate for men during 2012
2. Suppose I were to tell you that there are 5.2 million white females with diabetes in the United States 20 years and older out of a population of 84.7 million, and 2.2 million black females with diabetes out of a population of 14.0 million. What is the ratio (white to black) of females with diabetes? What does this tell you? What does this not tell you?
3. Out of all white women age 20 and above, what proportion of them have diabetes? What does this tell you? What does it not tell you
4. What are the rates of diabetes (per 100) of white and black women 20 and above and how do they compare?
5. Of the 81.1 million white males aged 20 and older, 27.1 million have high blood pressure. Of the 12.7 million black males, 5.3 million have high blood pressure. What is the ratio of hypertension among whites versus blacks, the proportion of hypertension among white males, the rates (per 100) of hypertension among white and black males, and the relative risk of hypertension among black versus white males?
