Ojo: Utilice el módulo estadístico de su calculadora para obtener los valores a 4 espacios decimales. Data on the PH for rain has been collected as shown below. It is known that the data comes from the Normal Distribution. Historically the mean value for the PH has been 5.0 . Abajo se muestra la data recopilada sobre el PH de la lluvia. Se sabe que la data viene de una distribución normal. Históricamente el valor promedio del $\mathrm{PH}$ ha sido 5.0.
