A local newspaper wanted to survey local residents to see how they have been impacted by inflation. To do this, the newspaper sends an intern to sit outside the Yoke's supermarket in West Richland from 5:00-8:00 PM on a Thursday evening and talk to the first 50 people willing to respond to the survey. In the space provided, explain what types of issues may arise by allowing participants to choose whether or not to participate in the survey. Consider what types of bias may occur. What other types of issues may occur in this scenario? Use complete sentences for full credit. Your response should probably use words like voluntary and/or convenience and/or bias!
