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? the museum staff who set up all of the current exhibits a group of classmates every fifth person who leaves the museum one afternoon every person buying a ticket to the science museum
Answer
# Brief Explanations:
To find the most popular exhibit, we need a representative sample of museum - goers. Museum staff may have a biased view, classmates may not be representative of all museum visitors, and people buying tickets may not have seen the exhibits yet. Sampling every fifth person leaving the museum one afternoon gives a sample of people who have actually visited the exhibits.
# Answer:
C. every fifth person who leaves the museum one afternoon
