a. What is the sample? What is the population?

b. The principal wants the group to be representative of the school population. Is the principal’s method of selecting students a good method? Explain your reasoning. If you think the principal’s method is not adequate, explain how you think the principal should select students.

a. Population is all the students in the school, while the sample is the students that contact her.

b. Not representative, not good method. Selecting students needs to be related to the reason for the conference, which is not stated.
