sadie wants to know how well food and drinks sell at a baseball game. she plans to survey a representative sample of fans at the game. which method is most likely to give sadie a representative sample of fans at the game? survey all fans in seats that cost less than $10. survey all fans in line at a food stand. survey all fans whose ticket number ends in 3 or 7. survey all fans at the game.

Answer

Brief Explanations:

  • Si se surveyan solo los fans en asientos que cuestan menos de $10, se está sesgando hacia los fans con menos presupuesto, lo que no representa a todos los fans.
  • Si se surveyan los fans en la fila de un puesto de comida, es probable que estén más interesados en la comida y bebida que la media de los fans, lo que es un sesgo.
  • Si se surveyan todos los fans, aunque sería una muestra representativa, puede ser muy difícil de implementar.
  • El método de surveyar a los fans cuyos números de boleto terminan en 3 o 7 es un método aleatorio que tiene más probabilidades de representar a la población general de fans en el juego.

Answer:

Survey all fans whose ticket number ends in 3 or 7.
