Solution

Para resolver este problema, primero necesitamos calcular la proporción de visitantes que no compraron ningún disfraz en el día dado. Luego, aplicaremos esta proporción al número esperado de visitantes la próxima semana.

  1. Calcular el número total de visitantes en el día dado: Total de visitantes=138(no compraron)+185(compraron uno)+25(compraron maˊs de uno)=348 \text{Total de visitantes} = 138 (\text{no compraron}) + 185 (\text{compraron uno}) + 25 (\text{compraron más de uno}) = 348

  2. Calcular la proporción de visitantes que no compraron ningún disfraz: Proporcioˊn de no compradores=138348 \text{Proporción de no compradores} = \frac{138}{348}

  3. Simplificar la fracción: Proporcioˊn de no compradores=1383480.3966 \text{Proporción de no compradores} = \frac{138}{348} \approx 0.3966

  4. Aplicar esta proporción al número esperado de visitantes la próxima semana: Nuˊmero esperado de no compradores=0.3966×1900753.54 \text{Número esperado de no compradores} = 0.3966 \times 1900 \approx 753.54

  5. Redondear al número entero más cercano: Nuˊmero esperado de no compradores754 \text{Número esperado de no compradores} \approx 754

Por lo tanto, se espera que aproximadamente 754 visitantes no compren ningún disfraz la próxima semana.
