The Black Women's Health Study, a study of risk factors for coronary heart disease in African American women, consisted of 352 women who reported having had a heart attack (cases), who were matched on age with 1760 controls (Am J Epi 1999; 150:904-909). The following data summarize some of the findings.

History of Heart Attack in a Parent	Case	Control	Total
No	169	1082	1251
Yes: at age 50+	91	329	420
Yes: before age 50	53	106	159
Total	313	1517	1830

1) In the BWHS, the odds of having a parental history of heart attack at any age for cases is:

2) In the BWHS, the Odds Ratio of having a parental history of heart attack at any age for cases compared to controls is:

3)In the BWHS, a 99% Confidence Interval for the true population Odds Ratio of parental history of heart attack at any age for cases as compared to controls is:

Coronary heart disease is caused by a buildup of plaque in the arteries that supply blood to the heart. When the flow of blood to the heart is restricted or blocked, the heart can be damaged due to a lack of oxygen. Further, if a large piece of plaque buildup gets dislodged from an artery wall, it can get stuck in other arteries throughout the body, including arteries in the brain. For simplicity, let's assume that the artery is cylindrical...
