DETERMINACION DE MUESTRAS

1) FORMULA: n= Z² pqN

NE² + Z² pq

DATOS: n= 58500

Z= 1.96

p= 0.7

q= 0.3

E= 0.05

OPERACION: n= (1.96²) (0.7) (0.3) (58500)

(58500 X 0.05²) + (1.96² X 0.7 X 0.3)

n= 47194.056 n= 47194.056

146.25 + 0.806736 147.056736

n= 320.92

R= 321 sacos

2) FORMULA: n= Z² pq

E²

DATOS: Z= 1.96

p= 0.5

q= 0.5

E= 0.1

OPERACIÓN: n= (1.96²) (0.5) (0.5)

(0.05²)

n= 0.9604

0.01

n= 96.04

R= 96 mujeres

3) FORMULA: n= Z² pqN

NE² + Z² pq

DATOS: n= 480

Z= 1.96

p= 0.5

q= 0.5

E= 0.04

OPERACIÓN: n= (1.96²) (0.5) (0.5) (480)

(480 x 0.04²) + ( 1.96² x 0.5 x 0.5)

n= 460.992 n= 460.992

0.768 + 0.9064 1.7284

n= 266.71

R= 267 niños (as)
