Respuesta = En una distribución normal, la zona de aceptación representa el área donde no rechazamos la hipótesis nula, mientras que la zona de rechazo es el área donde sí la rechazamos. El área total bajo la curva normal es siempre 1 (o 100%). ### Dado: - **Zona de aceptación** = 90% = 0,90 - **Zona de rechazo en la cola superior** (que corresponde al área fuera de la zona de aceptación) = 10% = 0,10 El nivel de significancia \( \alpha \) corresponde a la probabilidad de rechazar la hipótesis nula cuando es verdadera, que es exactamente el área en la zona de rechazo. Como la zona de rechazo está en la **cola superior** y es el 10% de la distribución, concluimos: - \( \alpha = 0.10 \) (o 10%). ### Conclusión: El valor de \( \alpha \) es **0,10** (o 10%).

there are 500,000 bacteria at the end of a pin point. 1000 bacteria can make a person sick. then bacteria at the tip of a pin point can make 500 people sick. Also, many people do not know that bacteria can (reproduce). Let's say there are 5 bacteria and we leave it for 15 minutes. bacteria will multiply to 10. if left for up to 30 minutes, 20 bacteria will form. if left up to 45 minutes. bacteria will multiply up to 40. every 15 minutes the bacteria will double 2. if you start with five bacteria that reproduce every 15 minutes, how manu bacteria would you have after 12 hours ?
