A continuación, se muestran algunos problemas de ejemplo de cómo se debe emplear la tabla tipificada de la normal aquí expuesta.

Problemas: Distribución Normal Tipificada.
Problema 1.
Problema 2.


NOTA: Existen diferentes tipos de tablas tipificadas de la distribución normal, en Aqueronte se ha optado por la que cubre la mitad del área la curva de Gauss, por lo tanto, el resultado se tendrá que sumar o restar la otra mitad (0.5). Aún así, el resultado final debe ser igual independientemente de la tabla escogida.
