For a political science class, students gathered data for a supporters profile of the two candidates for senator, Hill and Dale. One student stationed herself at a busy intersection and categorized the cars turning left according to whether or not they signaled the turn and whose bumper sticker was displayed.
After 2 hours, she left with the frequencies shown in the accompanying table. Test these data with a x2 test. Write a paragraph of explanation for the supporters profile that can be understood by students who haven't studied statistics. Begin the paragraph with appropriate details about how the data were gathered.
