Answer

Answer:

55.7, 60.3

Explanation:

Step1: Aplicar la regla empírica

La regla empírica dice que en una distribución normal, aproximadamente el 68% de los datos está dentro de 1 desviación estándar del promedio.

Step2: Calcular el límite inferior

Restar la desviación estándar al promedio: $58 - 2.3=55.7$.

Step3: Calcular el límite superior

Sumar la desviación estándar al promedio: $58 + 2.3 = 60.3$.
