Question 6: (6 marks) Sarah is 39 and expecting her first child. As a mature mother, she is worried about the possibility of having a baby with Down's Syndrome (DS). The chances of a 39-year-old mother having a baby with DS are approximately 1 in 100. Just to be on the safe side, Sarah decides to have a maternal blood serum test to check for chromosomal abnormalities. If the baby has DS, then the blood serum test will deliver a positive result 90% of the time. There is, however, a small "false positive" rate of 7%. Suppose 1000 39-year-old mothers choose to get the maternal blood serum test. (i) How many mothers will get a "true positive," i.e., the baby has DS and the test returns a positive result? (1 mark) (ii) How many will get a "false positive," i.e., the baby does not have DS, but the test returns a positive result? (1 mark) (iii) How many mothers will get a "false negative," i.e., the baby has DS, but the test returns a negative result? (1 mark) (iv) Suppose Sarah gets a positive test result. Using the numbers from the previous parts of this question, what is the posterior probability that her baby has Down's Syndrome? How much larger is this posterior probability compared to her prior probability? You should briefly explain the steps you take to arrive at your answer. (3 marks)
