A cable company wants to find out the average number of hours its customers spend watching cable television. Which group would best represent a sample of the population?

A representative sample should be drawn from the population the company wants to study: its current customers. The monthly billing list includes those customers, so randomly choosing 100 people from it can provide a suitable sample. The other groups are passersby, former customers, or customers of different companies, so they do not represent the company’s current customers.
