(b) 0.2514
(c) 0
Step-by-step explanation:
Let <em>X</em> denote the heights of women in the USA.
It is provided that <em>X</em> follows a normal distribution with a mean of 64 inches and a standard deviation of 3 inches.
(a)
Compute the probability that the sample mean is greater than 63 inches as follows:
Thus, the probability that the sample mean is greater than 63 inches is 0.2061.
(b)
Compute the probability that a randomly selected woman is taller than 66 inches as follows:
Thus, the probability that a randomly selected woman is taller than 66 inches is 0.2514.
(c)
Compute the probability that the mean height of a random sample of 100 women is greater than 66 inches as follows:
Thus, the probability that the mean height of a random sample of 100 women is greater than 66 inches is 0.
Usando probabilidad condicional, se encuentra que hay una probabilidad de 0.0186 = 1.86% que la persona esta realmente autorizada para ingresar.

Probabilidad Condicional
En que:
- P(B|A) es la probabilidad de que ocurra el evento B, dado que A sucedió.
es la probabilidad de que ocurran tanto A como B.
- P(A) es la probabilidad de que ocurra el evento A.
En este problema:
- Evento A: Persona rechazada.
- Evento B: Autorizada.
La probabilidad de una persona ser rechazada es:
de 95% = 0.95(autorizada).
de 5% = 0.05(non autorizadas).
O sea:
La probabilidad de una persona estar autorizada y ser rechazada es:
¿Cuál es la probabilidad que la persona esta realmente autorizada para ingresar?
Probabilidad de 0.0186 = 1.86% que la persona esta realmente autorizada para ingresar.
