Suppose that a polygraph is 90% accurate (it will correctly detect 90% of people who are lying and it will correctly detect 90% of people who are telling the truth).  The 2000 employees of a company are given a polygraph test during which they are asked whether they have been stealing from the company.  All of them deny stealing, when in fact 1% of the employees actually have been stealing.  Assume that anyone whom the polygraph operator finds untruthful is accused of lying.



a.  How many employees are accused of lying?  Of theses, how many were actually lying and how many were telling the truth?  What percentage of those accused of lying were falsely accused?
b.  How many employees are found truthful?  Of these, how many were actually truthful?  What percentage of those found truthful were really truthful?
