Administrators at a Large Hospital Are Concerned About the Possibility

Administrators at a large hospital are concerned about the possibility of drug abuse by people who work there. They decide
to check on the extent of the problem by having a random sample of the employees undergo a drug test. Several plans for
choosing the sample are proposed.
a. There are four employee classifications: doctors, medical staff (nurses, technicians, etc.) office staff, and support staff
(custodians, maintenance, etc.). Randomly select ten people from each category.
b. Each employee has a 4-digit ID number. Randomly choose 40 numbers.
c. At the start of each shift, choose every tenth person who arrives for work.
d. Randomly select five departments and test all the people who work in those department - doctors, nurses, technicians,
clerks, custodians, etc.
-Listed below are the names of the 20 pharmacists on the hospital staff. Use the random
numbers listed below to select three of them to be in the sample. Clearly explain your
method. $\begin{array}{|c|c|}\hline \text { Pastore } & \text { Back } \\\hline \text { Spiridinov } & \text { Ahl } \\\hline \text { Hedge } & \text { MacDowell } \\\hline \text { Schissel } & \text { Novelli } \\\hline \text { Lavine } & \text { Kaplan } \\\hline \text { Highland } & \text { Roundy } \\\hline \text { Grubb } & \text { Markowitz } \\\hline \text { Glass } & \text { Davies } \\\hline \text { Golkowski } & \text { Reeves } \\\hline \text { Janis } & \text { Yen } \\\hline\end{array}$
