Answer

Explanation:

Step1: Record la fórmula de varianza

La varianza ($\sigma^{2}$) es el cuadrado de la desviación estándar ($\sigma$).

Step2: Calcular la varianza

Dado que $\sigma = 2.5$, entonces $\sigma^{2}=(2.5)^{2}=6.25$.

Step3: Redondear al décimo más cercano

Redondeando 6.25 al décimo más cercano obtenemos 6.3.

Answer:

6.3
