A genetic disorder occurs with probability 1/10,000. There is a test for this genetic disorder. If you have the disorder, then you test positive 99% of the time. If you don’t have the disorder, then you test negative 95% of the time. If you test positive, what is the probability that you have the disorder?

2. Tay-Sachs disease is a genetic disorder caused by a mutation on chromosome 15 that is believed to occur in roughly 1 in 320000 babies in the U.S. As part of a cutting-edge genomics company, you've designed a new test for Tay-Sachs that is 99.2% accurate (ie, gives a positive result) in those babies that have the disorder, and 97% accurate (i.e. gives a negative result) in babies that don't have the disorder. Suppose...

Suppose that the probability for cancer is .01. And the probability of getting a positive test result, given you’ve got cancer is .72, and the probability of getting a negative test result, given you don’t have cancer is .72 as well. What is the probability of cancer, if the test is negative?

A genetic test is use to determine if people have a disposition for thrombosis, which is the formation of a blood clot inside a blood vessel that obstructs the flow of blood though the circulatory system. It is believed that 3% of people actually have this predisposition. The genetic test is 99% accurate if a person has the predisposition, meaning that the probability of a positive test result when a person actually has the predisposition is 0.99. The test is...

Assume 50% of the world's population has a particular genetic condition. A blood test for the condition is available, but it is not 100% accurate. For those who do not have the genetic condition, the blood test will return a positive result 5% of the time. Additionally, for those who have the genetic condition, the test returns a negative result 8% of the time. Consider the experiment that an individual is randomly selected and tested for the genetic condition. Define...

Question 2 1/1 pts 5% of a certain population has a particular genetic condition. A test for this condition gives a positive result with probability 20% when applied to a randomly selected individual from this population, and it gives a positive result 99% of the time, when the randomly selected individual really has the condition. Suppose a randomly selected individual from the population is tested. Given that the individual tests positive for the condition, what is the probability that the...

(1 point) Klinefelter syndrome, alternatively known as XXY, is a genetic disorder characterised by the presence of an extra X chromosome. The disorder only affects males. Suppose a researcher estimates that the probability that a newborn male will have Klinefelter syndrome is 0.0014. Suppose that a particular hospital delivers 1797 male babies in a year. Part a) Using a binomial model, what is the probability that more than two of the male births have Klinefelter syndrome? Give your answer to...

The probability of a randomly selected adult having a particular genetic defect is 0.02. Suppose that a diagnostic test is available and that the probability an adult who has the genetic defect tests positive is 0.97. There is a small probability, 0.01, that a person who does not have this genetic defect will test positive. What is the probability that a randomly selected adult does not have the genetic defect, given the test was positive?

Suppose that swine flu (for the purposes of this exercise) affects 1 in 10,000 people in the U.S. The test is known to have a false positive rate of 0.01 -- that is, 1% of all positive tests are actually negative. The probability of a false negative is zero – that is, 100% of all negative tests are truly negative. You test positive. What is the probability that you actually have the swine flu? Hint: Define the event ? as...
