Question

eli wants to know which exhibit at a science museum is the most popular. which is the best group to survey to find this information? every person buying a ticket to the science museum the museum staff who set up all of the current exhibits every fifth person who leaves the museum one afternoon a group of classmates

Explanation:

To find the most popular museum exhibit, the survey group must represent all museum visitors. Surveying every fifth person leaving one afternoon is a random, representative sample of actual exhibit attendees. Surveying all ticket buyers is inefficient and unnecessary; staff have biased perspectives; classmates are a non-representative niche group.

Answer:

every fifth person who leaves the museum one afternoon
