Question

7. Chelsea conducted a survey to determine which candidate is leading the race for ninth-grade class president byasking 50 ninth-grade girls in the cafeteria how they would vote in the election ?

Answer 1

Option B is correct.

The only reason why Chelsea's prediction might be wrong is that She did not include all of the ninth graders in the survey.

Step-by-step explanation

Surveys provide an idea of how the entire group of people feel about a subject matter. So, picking 50 ninth grade girls to survey will provide an idea of how the election results will be like.

But since everyone is voting in the election, the prediction using the survey results might be wrong, since it doesn't include all the ninth graders in the survey.

Hope this Helps!!!
