4 points Save A Suppose you must establish regulations concerning the maximum number of people who can occupy an elevator. A study of elevator occupancies indicates that, if eight people occupy the elevator, the probability distribution of the total weight of the eight people has a mean equal to 1,250 pounds and a variance equal to 9,800 lbs- Assume that the probability distribution is approximately normal. We are interested in the probabilities of exceeding 1,300 pounds and 1,500 pounds in the elevator. Suponga que se desea establecer regulaciones sobre el maximo de personas que pueden ocupar un elevador. Un estudio de ocupacion indica que, si ocho personas ocupan el elevador, la distribucion de probabilidad del peso total para las ocho personas tiene un promedio de 1,250 libras y una varianza de 9,800 lbs . Asume que la distribucion de probabilidad es aproximadamente normal. Estamos interesados en las probabilidades de exceder 1,300 libras y 1,500 libras en el elevador. What is necessary to solve for the required probabilities? Mark every answer that applies. Que de lo siguiente es necesario para calcular las probabilidades requeridas? Marca todas las que apliquen. D a. Look for the corresponding probability in a Normal Probability Table. Busca la probabilidad que corresponda en una tabla de probabilidad normal. b. Convert the random variable from N (u, o) to N (0,1). Convierte la variable aleatoria de N (u, o) a N (0,1) O c Define the random variable. Define la variable aleatoria. O d. Convert the random variable from N (0,1) to N (u, o). Convierte la variable aleatoria de N (0,1) a N (u, o)
