Solution 1

Para resolver esta pregunta, necesitamos usar la fórmula de la media (µ) de una población, que es:

μ=ΣXN \mu = \frac{\Sigma X}{N}

Donde:

  • μ \mu es la media de la población.
  • ΣX \Sigma X es la suma de todos los valores en la población.
  • N N es el número de puntuaciones en la población Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
