Explanation:

Step1: Determinar el rango

El porcentaje de encuestados que prefirieron al Candidato A es del 36% con un margen de error del 3%. El rango real se calcula sumando y restando el margen de error al porcentaje de la muestra.
El límite inferior es $36 - 3=33\%$.
El límite superior es $36 + 3 = 39\%$.

32.3%
