A political consulting firm wants to determine the characteristics of voters when it comes to issues involving alternative energy. The researchers recruit a group of participants and randomly assign them to one of three groups: Group 1 will be the control group, and they will not be exposed to any advertising materials; Group 2 will be shown a print advertisement that will be used in a postal mailing; and Group 3 will be shown a video advertisement that will be aired on television. Finally, each participant will indicate his or her voting intentions for Proposition 86, which involves tax deductions for hybrid cars on a 1 to 7 scale (1 = Will definitely vote no . . . 7 = will definitely vote yes). Additionally, participants will indicate their voting intentions for Proposition 99, which involves rebates for installing home solar energy using the same type of (1 to 7) scale.
