Question: For each of the following, use a one-way data table to see how the posterior probability of being a drug user, given a positive test, varies as the indicated input varies. Write a brief explanation of your results.
a. Let the input be the prior probability of being a drug user, varied from 0.01 to 0.10 in increments of 0.01.
b. Let the input be the probability of a false positive from the test, varied from 0 to 0.10 in increments of 0.01.
c. Let the input be the probability of a false negative from the test, varied from 0 to 0.10 in increments of 0.01.
