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)

Answer:

Width: \frac{3in}{8ft} = \frac{5in}{x} (cross multiply)

   = 40 ÷3 ≈ 13.3ft

Width: \frac {3in}{8ft} = \frac{6.5in}{x}

   = 17.3

A=e × w

   = 13.3 × 17.3 ≈ 230.09 ≈ 230.1
