Answer 1

People stopped and swabbed in airport security lines represent a 'Representative Sample' of all travelers, as they are a selection intended to represent the overall group passing through security.

Step-by-step explanation:

At airports, some people are stopped in the security line and their hands and luggage are swabbed for chemicals; those individuals may be considered a Representative Sample of all the people that pass through security. This is because a representative sample is a subset of individuals selected from the larger population that is intended to represent a population in research. In the context of psychological research, the individuals who are swabbed would represent the larger group of people passing through security, and they can provide information about the larger group from a security standpoint.
