The circuit judges in a rural county are considering a change in how jury pools are selected for felony trials. They ask the administrator of the courts to assess the county residents’ reaction to changing the requirement for membership in the jury pool from the current requirement of all registered voters to a new requirement of all registered voters plus all residents with a current driver’s license. The administrator sends questionnaires to a random sample of 1,000 people from the list of registered voters in the county and receives responses from 253 people.
