Want to draw a sample from populations

  Suppose that you want to draw a sample from each of the following populations. Devise a sampling plan for each by (1) indicating the unit of analysis, (2) clearly defining the target population, (3) constructing the sampling frame, and (4) selecting and justifying an appropriate sampling design (e.g., simple random sampling, stratified random sampling, purposive sampling). You must explain why for each question above.
