Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Suppose 5 out of every 10,000 individuals in a country has a rare disease. A test for the disease exists. Individuals known to have the disease test positive 99% of the time. Individuals known to be free of the disease test negative 98% of the time. Suppose an individual from the country is selected at random (with all being equally likely to be selected) and given the test. Given that the individual tests positive, what is the probability that he in fact has the disease? Give the probability as a decimal number to six decimal places.
