Answer:

a) 2.1186

b) 13.591%

Step-by-step explanation:

Resolvemos usando la fórmula de puntuación z

z = (x-μ) / σ, donde

x es la puntuación bruta =

μ es la media de la población = 500g

σ es la desviación estándar de la población = 5 g

a) Calcula la probabilidad de encontrar una caja que pese menos de 496 gramos.

Para x = 496g

z = 496 - 500/5

z = -0.8

Valor de probabilidad de Z-Table:

P (x <496) = 0.21186

La probabilidad de encontrar una caja que pese menos de 496 gramos es 0.21186

b) ¿Qué porcentaje de cajas pesan entre 505 gy 510 g?

Para x = 505 g

z = 505 - 500/5

z = 1

Valor de probabilidad de Z-Table:

P (x = 505) = 0.84134

Para x = 510g

z = 510 - 500/5

z = 2

Valor de probabilidad de Z-Table:

P (x = 510) = 0.97725

La probabilidad de cajas que pesen entre 505 gy 510 g

P (x = 510) - P (x = 505)

= 0.97725 - 0.84134

= 0.13591

Conversión a porcentaje

= 0.13591 × 100

= 13.591%

El porcentaje de cajas que pesan entre 505g y 510g es del 13.591%

Answer:

B
