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)
Try looking at the question like this.
You have 0 tenths (00)
You have 0 hundreds (000)
<u>You have 9 thousands (9000)</u>
You have 50 thousands, (50,000)
You have 700 thousands (700,000)
You have 6 millions (6,000,000).
To determine which number it is rounded to, simply look at which has an actual number in it. 9,000ths is the first slot with a number, which means the number is rounded to the nearest thousand. If it was 6,759,800, it would be rounded to the nearest hundredth and so on...
Third angle =180° - (149° + 9°)
= 22°
Thanks me if is correct!
The answer is: 7x
I hope this helped
Hello this is my easy way to multiply with zeros.What you do is ignore the zero like its not even there next you multiply whats left so we multiply 3 x 4 and that is 12.next we add the zero and that's it.Hoped I Helped! :D
