In 1960 sociologists studied a random sample of 1,018 families that consisted of a husband, a wife, and at least one child. Of those families, 5.8 percent reported that the wife was the primary wage earner of the family. In 2011 the study was replicated with a random sample of 1,013 families that consisted of a husband, a wife, and at least one child. Of those families, 22.3 percent reported that the wife was the primary wage earner of the family. Which of the following represents a 99 percent confidence interval for the difference between the proportions of families that consisted of a husband, a wife, and at least one child from 1960 to 2011 that would have reported the wife as the primary wage carner?

Lee el siguiente planteamiento y resuelve los problemas:

Un globo electrostáticamente cargado ejerce una fuerza de atracción sobre un papel de tal forma que se pueden identificar dos cargas positivas en la periferia del globo y una negativa en la periferia del papel. Las cargas del globo y del papel están colocadas en los vértices de un triángulo equilátero cuyos lados tienen una longitud de 5 cm, tal como se muestra en la figura. Se sabe que la carga q1 tiene polaridad negativa con un valor de 20 μC (microcoulomb), la carga q2 tiene polaridad positiva con una magnitud de 10 μC y la carga q3 también tiene polaridad positiva con una intensidad de 30 μC.


Calcula la fuerza de q3 sobre q1. Para ello, hay que sustituir los valores de las respectivas cargas en la ecuación de la ley de Coulomb y el valor de la distancia d , la cual corresponde a la separación entre q1 y q3.

Realiza el cálculo de la fuerza de q2 sobre q1.

a. Utiliza el plano cartesiano para graficar los resultados de las fuerzas solicitadas.

Determina la magnitud de la fuerza de atracción resultante que ejercen las cargas q2 y q3 sobre q1 y el ángulo del vector de la resultante.

a. Utiliza el plano cartesiano para graficar el resultado, de la magnitud de la fuerza de atracción.
