A teacher needs to find out how many seventh-grade students will be going on a field trip. Which best describes the population that the teacher should survey?

Surveying the parents of the seventh-grade students can provide that information. The parents of all students and every student or teacher in the school include people who are not part of the group the teacher needs to count.
