Let's say you want to determine the mean salary of officers in XYZ County, based on your sample of officers from your town. What kind of sampling would that be? Is that appropriate for the purpose at hand? What might be a better sampling plan?

Using an appropriate method, obtain a random sample of 30 from your population.

Collect your data in an Excel spreadsheet with column headings Last Name, First Name, Salary, and Pension Months. Note that you will need to check to make sure you are not selecting any firemen, just police. (Tutor-YOU DO NOT NEED TO PROVIDE me an EXCEL) (just answer question below as best you can)

What sampling method did you use, and why?
