A random sample of 863 births in a state included  429 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  0.514. Do these sample results provide strong evidence against that​ belief?   Construct a 95​% confidence interval estimate of the proportion of boys in all births.   Do these sample results provide strong evidence against that​ belief?     A.

Construct a 95​% confidence interval estimate of the proportion of boys in all births.

 

Do these sample results provide strong evidence against that​ belief?

 

 

A.

There is not strong evidence against 0.514 as the value of the proportion of boys in all births because 

0.514 is not contained within the 95% confidence interval.

 

 

B.

There is strong evidence against 0.514 as the value of the proportion of boys in all births because 0.514 is not contained within the 95% confidence interval.

 

 

C.

There is strong evidence against 0.514 as the value of the proportion of boys in all births because 0.514 is contained within the 95% confidence interval.

 

 

D.

There is not strong evidence against 0.514 as the value of the proportion of boys in all births because 0.514 is contained within the 95% confidence interval.
