Sampling from a Population
ex. There are 435 voting members of the House of which 193 are currently democrats.
- Suppose we want to select a random sample of 18 members of the House of Representatives to determine the views of the Congress on the legalization of marijuana in DC.
Potential Concerns:
- What’s the likelihood that a randomly selected sample would contain all Democrats?
- What’s the likelihood that a randomly selected sample would contain no Democrats?
