external information you have.External population should cover the

For example:
Municipality               Students
1                           2,000
2.                          3,000
.
.

160                         8,000

Total                      70,0000

Male students:  50,000
Female students 20,000

If you have numbers like these, why is the total NOT  the sum of the your
numbers?

I assume that the target population is "children in all municipalities".
Is this right? Is this the same as "students in all municipalities?"  If
not, what is the target population?

Describe the sample.  Was any part of the target population excluded in
advance (e.g. some municipalities were not eligible for inclusion in the
sample?)
