Random Sampling and Survey Efficiency

Michael and Kevin debate the best way to survey students at Kennedy Middle School about their interest in sports. Michael suggests surveying every student, while Kevin proposes using a random sample of 50 students. Kevin's plan is deemed more efficient as it saves time and still represents the entire population accurately.

What is Kevin's main concern about Michael's plan?

• It will be too expensive

• It will take too long

What is a key feature of a random sample?

• Every person has an equal chance of being selected

• Only the most athletic students are chosen

• Only students who volunteer are chosen

How does a random sample represent the entire population?
