Rudiy27

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)

A bag contains yellow marbles and blue marbles, 73 in total. The number of yellow marbles is 7 more than 5 times the number of b
Roman55 [17]

Answer:

number of yellow marbles=62.

Step-by-step explanation:

It is given that in a bag there are yellow marbles and blue marbles and the total number of marbles=73.

Let the number of Blue marbles=x, then according to the question, number of yellow marbles will be =5x+7.

Now, Total number of marbles= number of yellow marbles+number of blue marbles.

⇒73=x+5x+7

⇒73-7=6x

⇒66=6x

⇒x=11

Therefore, numberof blue marbles=x=11 and

number of yellow marbles=5x+7=5(11)+7=55+7=62.
