Explanation:

Step1: Identificar los valores extremos

El intervalo de confianza es de 470 a 516.

Step2: Calcular la diferencia

La diferencia entre los valores extremos es $516 - 470=46$.

Step3: Dividir la diferencia por 2

El margen de error se obtiene dividiendo la diferencia entre los valores extremos del intervalo de confianza por 2. Entonces, $\frac{46}{2}=23$.
