A random sample of 860 births in a state included 424 boys. Construct a \( 95 \% \) confidence interval estimate of the proportion of boys in all births. It is believed that among all births, the proportion of boys is 0.513 . Do these sample results provide strong evidence against that belief? Construct a \( 95 \% \) confidence interval estimate of the proportion of boys in all births. \( .460

4) Dentro de 11 años la edad de Pedro será la mitad del cuadrado de la edad que tenia hace 13 añc Calcula la edad de Pedro. \( x+\square)=\frac{(x-\square)^{2}}{0} \rightarrow x^{2}-\square x+\square=0 \rightarrow x=\frac{\square \pm \sqrt{\square^{2}-4 \times \square}}{2} \rightarrow x=\frac{\square-\square}{2}=\frac{\square}{2}=\frac{\square}{2} \) Respuesta/ La edad de Pedro es \( \square \) años
