Explanation:

The goal is to find the average hours of the cable - company's customers watching cable TV. A good sample should be representative of the population of the company's customers. The first option includes non - customers passing by the office. The second option includes customers who canceled and may have different viewing habits. The third option includes customers of other companies. The fourth option, 100 customers chosen from the monthly billing list, is most representative of the company's current customer base.

100 of the company's customers chosen from the monthly billing list
