Based upon my sister's age and other genetic factors, Charlotte's risk for Down
Syndrome was only 1 in 350. During the sonogram, the doctors tested for Down
Syndrome by measuring the nuchal translucency. This diagnostic tool has an 80%
sensitivity and a 95% specificity. Charlotte (as a fetus) tested positive for Down
Syndrome. When she tested positive, what was the probability that she would have
Down Syndrome? Warning: You answered this question in the preparation exercise,
but now you know more. Use your new information and Bayes Theorem to update
your answer.
