The manager of a sports arena wants to learn more about the financial status of the people who are attending an NBA basketball game. He would like to give a survey to a representative sample of the more than 20,000 fans in attendance. Ticket prices for the game vary a great deal: seats near the court cost over $100 each, while seats in the top rows of the arena cost $25 each. The arena is divided into 30 numbered sections, from 101 to 130. Each section has rows of seats labeled with letters from A (nearest the court) to ZZ (top row of the arena).
1. Which would be a better way to take a stratified random sample of fans: using the lettered rows or the numbered sections as strata? Explain.
2. Which would be a better way to take a cluster sample of fans: using the lettered rows or the numbered sections as clusters? Explain.
