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...

A doctor knows from experience that 10% of the patients to whom she gives a certain drug will have undesirable side effects. Among the 13 patients to whom she gives the drug, find the following probabilities. (Give your answers correct to three decimal places.) (a) Find the probability P(At most two will have undesirable side effects). (b) Find the probability P(At least two will have undesirable side effects).[Hint: apply complement rule, P(at least 2) = 1 - p(less than 2)...

To prevent developing a certain type of cancer, Health Canada
organize a di- agnostic test. The false positive and negative rates
for this diagnostic test are five percent and four percent,
respectively. Assume that five percent of the population has this
type of cancer.
1. If a randomly selected person has a positive test result,
what is the prob- ability that the person has this type of
cancer?
2. The test is administrated twice on the same patient. Assume

Use the following results from a test for marijuana use, which is provided by a certain drug testing company. Among 141141 subjects with positive test results, there are 2626 false positive results; among 151151 negative results, there are 44 false negative results. If one of the test subjects is randomly selected, find the probability that the subject tested negative or did not use marijuana. (Hint: Construct a table.) The probability that a randomly selected subject tested negative or did not...
