Paso 1: Contar los puntos para cada número de letras

El gráfico muestra el número de estudiantes que tienen un apellido con una longitud específica. Cada punto representa un estudiante. Contamos los puntos sobre cada número en el eje horizontal:

  • 3 letras: 1 estudiante
  • 4 letras: 4 estudiantes
  • 5 letras: 1 estudiante
  • 6 letras: 1 estudiante
  • 7 letras: 2 estudiantes
  • 10 letras: 1 estudiante
Paso 2: Sumar el número de estudiantes

Sumamos el número de estudiantes de cada categoría: 1 + 4 + 1 + 1 + 2 + 1 = 10

Respuesta final

\( \boxed{10} \) estudiantes fueron encuestados.
