Question
Please answer all questions with detailed solutions
The incidence of a certain disease in the population is estimated
to be 0.5%. That is, the probability of a randomly selected person having the disease
is 0.005. A test for this disease is 90% accurate (i.e., it will positively identify a
person who has the disease with a probability of 0.9). On the other hand, the test
produces false positives with a probability of 0.02. If a person tests positive for the
disease, what is the probability that the individual actually has the disease? (Round
to the nearest 4 decimal places)
