Birth control in schools? What do adults believe about the role of high schools in providing birth control? Are opinions different in urban, suburban, and rural areas? To find out, researchers wanted to ask adults this question:

Which would you prefer for the public schools in your community? Provide birth control only to those students who have the consent of their parents.

Provide birth control to all students who want it. Not provide birth control to any student.

Because most people live in heavily populated urban and suburban areas, an SRS might contain few rural adults. Moreover, it is too expensive to choose people at random from a large region. We should start by choosing school districts rather than people. Describe a suitable sample design for this study, and explain the reasoning behind your choice of design.
