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 fifth person who leaves the museum one afternoon the museum staff who set up all of the current exhibits a group of classmates every person buying a ticket to the science museum

Explanation:

To determine the most popular exhibit, we need a representative sample of museum visitors. Surveying every fifth person leaving one afternoon (first option) is a systematic sample but limited by time. Museum staff (second) don't represent visitor preferences. Classmates (third) are a biased, non - representative group. Surveying every person buying a ticket (fourth) includes all potential visitors, giving a comprehensive and representative sample of those who will experience the exhibits, making it the best group to survey.

Answer:

every person buying a ticket to the science museum
