5. The Triple Blood Test screens pregnant women for the genetic disorder, Down syndrome. This syndrome occurs in about 1 in 800 live births and arises from an error in cell division that results in a fetus having an extra copy of chromosome 21. The chance of having a baby with Downsyndrome increases after a woman is 35 years old. A study (J. Haddow et al.,New England Journal of Medicine, vol. 330, pp. 1114-1118, 1994) of5282 women aged 35 or...

Company A is developing a new pregnancy test. Based on their experiments, the test gives the correct result about 73% of the time, meaning the test result is positive when the person is pregnant, it is negative when the person is not pregnant. Suppose that 45% of women who take the test are pregnant. If the test result is positive, what is the probability that the person is truly pregnant? You can express your answer as a fraction, decimal, or...

A test for ovarian cancer has a 2% rate of false positives (i.e. 2% of women who don’t actually have ovarian cancer test positive) and a 0% rate of false negatives.   Data collected by the Cancer association estimates that 1 in every 2500 women over 35 years of age having ovarian cancer. Answer the following questions. [All numeric answers should be accurate to 6 decimal places] What is the probability that a randomly selected woman over the age of 35...

Researchers asked pregnant women if they are currently smoking during this pregnancy and afterwards followed them through childbirth to test the association between smoking during pregnancy and stillbirth. Some smokers reported not smoking, resulting in some who were exposed being labeled as not exposed. What kind of bias is this? Do you think false reporting is more likely in one of the two groups (stillbirth, live birth) or equally likely?

The following hypothetical scenario concerns a population of women aged 50 and older. We know that 1% of this population has breast cancer at this time. The probability of testing positive on a mammogram is 90% for women who actually do have cancer (true positive result), and 8% for women who do not have it (false positive result). (a) Find the proportion of all negative mammogram results for this population. (8 points) (b) Given that a randomly selected woman has...

*8.21 Assume that the probability of breast cancer equals .01 for women in the 50–59 age group. Furthermore, if a woman does have breast cancer, the probability of a true positive mammogram (correct detection of breast cancer) equals .80 and the probability of a false negative mammogram (a miss) equals .20. On the other hand, if a woman does not have breast cancer, the probability of a true negative mammogram (correct non detection) equals .90 and the probability of a...
