Question 10 (1 point) Juan is running for student council president against Sarah. The school conducts a
survey and found that 54% of the student body is planning on voting for Juan while
46% plan on voting for Sarah. The survey conducted has a margin of error of 3%.
Juan plans to stop campaigning, is this a wise decision?
