**John**, Wednesday, December 12, 2007 at 10:30pmThe answer here is C. We are looking to make in inference about a broad group (the population) by observing a small cross section of the group (the sample).

Take, for example, the recent Presidential Polls. Groups like Zogby will call a sample of 500 people to ask them who they might vote for. Then they will make inferences about the general population of the United States about who is leading the race, etc.

Hope that helps :)
