1. (Total: 3 points) Three hundred registered voters were selected at random, 30 from each of 10 Midwestern counties, to participate in a study on attitudes about how well the president is performing his job. They were each asked to answer a short multiple-choice questionnaire and then they watched a 20-minute video that presented information about the job description of the president. After watching the video, same 300 selected voters were asked to answer a follow-up multiple-choice questionnaire.
