Question

A random sample of 860 births in a state included 428 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 0.511. Do these sample results provide strong evidence against
that belief?
Construct a 95% confidence interval estimate of the proportion of boys in all births.
<p<(Round to three decimal places as needed.)
Do these sample results provide strong evidence against that belief?
OA. There is not strong evidence against 0.511 as the value of the proportion of boys in all births because 0.511 is contained within
the 95% confidence interval.
OB. There is not strong evidence against 0.511 as the value of the proportion of boys in all births because 0.511 is not contained
within the 95% confidence interval.
OC. There is strong evidence against 0.511 as the value of the proportion of boys in all births because 0.511 is not contained within
the 95% confidence interval.
OD. There is strong evidence against 0.511 as the value of the proportion of boys in all births because 0.511 is contained within the
95% confidence interval.
