The newspaper article “Folic Acid Might Reduce Risk of Down Syndrome” (USA TODAY, September 29, 1999) makes the following statement: “Older women are at a greater risk of giving birth to a baby with Down Syndrome than are younger women. But younger women are more fertile, so most children with Down Syndrome are born to mothers under 30.”
Let D =
- a. P(D|Y) = 0.001, P(D|YC) = 0.004, P(Y) = 0.7
- b. P(D|Y) = 0.001, P(D|YC) = 0.001, P(Y) = 0.7
- c. P(D|Y) = 0.004, P(D|YC) = 0.004, P(Y) = 0.7
- d. P(D|Y) = 0.001, P(D|YC) = 0.004, P(Y) = 0.4
- e. P(D|Y) = 0.001, P(D|YC) = 0.001, P(Y) = 0.4
- f. P(D|Y) = 0.004, P(D|YC) = 0.004, P(Y) = 0.4
