Question

look at this set of 5 numbers: 9 3 5 3 5 by how much would the mean increase if the number 8 replaced one of the 3s in the set?

Explanation:

Step1: Calcular la media original

La suma de los números originales es \(9 + 3+5 + 3+5=25\).
La media original es \(\frac{25}{5}=5\).

Step2: Calcular la suma después del reemplazo

Reemplazamos un \(3\) por un \(8\). La nueva suma es \(25-3 + 8=30\).

Step3: Calcular la nueva media

La nueva media es \(\frac{30}{5}=6\).

Step4: Calcular el aumento de la media

El aumento es \(6 - 5=1\).
