The county government in a city that is dominated by a large state university is concerned that a small subset of its population has been overutilized in the selection of residents to serve on county court juries. The county decides to determine the mean number of times that an adult resident of the county has been selected for jury duty during the past 5 years. They will then compare the mean jury participation for full- time students to that of nonstudents.
a. Identify the populations of interest to the county officials.
b. How might you select a sample of voters to gather this information?
