st: How do I demonstrate that a sample is randomly drawn from a population?

Dear statalisters,
I have two files:
1) The first file contains the grades of all population of Open
University students.
2) The second file contains the grades of Open University students,
who filled a questionnaire via the net.
I would like to show that the second file is a random sample drawn
from the first file.
The question is can I provide a statistical evidence that the sample
is indeed random? what are the appropriate commands in stata?
P.S. I thought to run the test of difference of means between two
populations. Having reconsidered, however, I'm not talking here about
two populations, but rather a sample,which is drawn from a given
population.
As always, your answers will be very much appreciated
