Members of the seventh grade math group have nominated a member of their group for class president. Every student in seventh grade will cast a vote. There are only 2 candidates in the race, so a candidate must receive at least 50 percent of the vote to be elected. It is expected to be a tight race, so the math group wants to conduct a survey to gain information on the prospects of their candidate. They do not have the time to interview all seventh graders in the school (even if they could contact them) so they decide to interview a sample of 40 students from that grade. They obtain the seventh grade list of names from their school office and select the sample form this list. They plan to ask each sampled student whether they plan to vote for their candidate or the other candidate. Aligns with 7.SP.A.
