Una compañía de yogurt controla su proceso de producción para tener bolsita con un promedio igual a 20 gramos de producto. El proceso deberá ser detenido cuando el promedio cambie de los 20 gramos. Por ello, tomaron 16 bolsitas, determinando una media de 19 gramos. A un nivel de significación de \( 5 \% \) y con una desviación estándar poblacional de 2 gramos, e deberá ser detenido el proceso?
