Lesson Worksheet

Q1:

What is a population?

Q2:

Why does the statement “All the clothing produced by a factory to measure the quality of that factory” not describe a simple random sample?

Q3:

Suppose your school has 500 students and you need to conduct a short survey on the quality of the food served in the cafeteria. You decide that a sample of 10 students should be sufficient for your purposes. So, you choose 10 students randomly out of the 500 and conduct the survey on them.

Is that considered a simple random sample?
