The following information applies to questions 10, 11, 12 and 13: Vietnam veterans who participated in a defoliation program were exposed to large amounts of a substance known as Agent Orange. This material was contaminated with a known toxin called TCDD (one of the most toxic forms of dioxin). To measure veterans’ levels of TCDD, blood tests were conducted. It was found that 150 tested Vietnam veterans had average blood levels of TCDD 10 times higher than the average of 50 service men who had served in Southeast Asia during World War II. (Agent Orange was not used during World War II.) Five Vietnam veterans had blood levels 40 to 60 times higher than the World War II veterans. ___10. From this you may conclude that: 1) exposure to Agent Orange significantly increased the amount of TCDD in the bodies of Vietnam veterans. 2) the 50 service men who served in Southeast Asia during World War II were an appropriate control group for comparing with the Vietnam veterans. 3) the study is definitive (gives an adequate answer). 4) an adequate control was not provided by this sampling design, since Agent Orange was not used during World War II. 5) an adequate control was not provided by this sampling design since World War II veterans were much older than the Vietnam veterans. ___11. Which description provides an adequate control with which to compare veterans’ TCDD levels? 1) military personnel serving in Europe. 2) military personnel serving in areas of Southeast Asia where Agent Orange was not used and who have been matched to the Vietnam veterans for age, weight, and smoking and drinking habits. 3) civilians in the United States using Agent Orange and who have been matched to the Vietnam veterans for age, weight, and smoking and drinking habits.
