Answer:
Intervalo de confianza
= (0.294, 0.386)
Step-by-step explanation:
La fórmula para el intervalo de confianza para la proporción se da como
p ± z × √p (1 - p) / n
Donde p = x / n
De donde de la pregunta anterior
x = 136 personas
n = 400 personas
p = 136/400
p = 0.34
z = puntuación z del intervalo de confianza del 95% = 1.96
Por lo tanto,
Intervalo de confianza =
0.34 ± 1.96 × √0.34 (1 - 0.34) / 400
= 0.34 ± 1.96 × √0.34 × 0.66/400
= 0.34 ± 1.96 × √0.000561
= 0.34 ± 1.96 × 0.0236854386
= 0.34 ± 0.0464234596
Intervalo de confianza
= 0.34 - 0.0464234596
= 0.2935765404
= 0.34 + 0.0464234596
= 0.3864234596
Hence:Intervalo de confianza
= (0.294, 0.386)
Its 5 years
worth = 18000
depriciation per year= 3
in 5 year car value= 18000 minus 5×3000= 3000
