Drug screening: A large company has instituted a mandatory employee drug screening program. Assume that the drug test used is known to be 99% accurate. That is, if an employee is a drug user, the test will come back positive ("drug detected") 99% of the time. If an employee is a non-drug user, then the test will come back negative ("no drug detected") 99% of the time. Assume that 2% of the employees of the company are drug users. In constructing the hypothetical two-way table, it is convenient to start by assuming that the company has 10,000 employees (10,000 is a large enough number to ensure that all calculations result in whole numbers). drug user non drug user Row Totals drug test: positive C drug test: negative D Column Totals 200 9800 10,000 Find the value for D
