A group of students wants to determine the favorite snack food at their school. They know they should use a sample because the student population at their high school is 5,000. What is the best way for them to get a random sample of 100 students? Ask the teachers at the school their opinions. Ask every 20th student until they reach 100 students. Ask the first 100 students that get off the bus in the morning. Ask all the students in the cafeteria during one of the four lunch periods.

    Miguel surveyed all the members of the junior high choir about their favorite class. The results from his survey are: Favorite Class Number of Students choir 19 math 7 history 5 English 9 science 4 Miguel concluded, from his results, that the favorite class among the entire student body would also be choir. Which is the best explanation of why his conclusion might not be true? The survey should have been conducted each day for a week. His sample group does not represent the entire student body. The survey should have been conducted with the eighth-graders only. The choir only meets one day a week.
