A genetic test is used to determine if people have a predisposition for thrombosis, which is the formation of a blood clot insid
e a blood vessel that obstructs the flow of blood through the circulatory system. It is believed that 3% of people actually have this predisposition. The genetic test is 98% accurate if a person actually has the predisposition, meaning that the probability of a positive test result when a person actually has the predisposition is 0.98. The test is 97% accurate if a person does not have the predisposition. What is the probability that a randomly selected person who tests positive for the predisposition by the test actually has the predisposition? (Round your answer to four decimal places.)
variance measures variability from the average or mean. It is calculated by taking the differences between each number in the data set and the mean.','.
