B. Upper H 0​: pequals0.514 Upper H 1​: pgreater than0.514

C. Upper H 0​: pequals0.514 Upper H 1​: pnot equals0.514

D. Upper H 0​: pequals0.514 Upper H 1​: pless than0.514

Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is nothing. ​(Round to two decimal places as​ needed.)

Identify the​ P-value for this hypothesis test. The​ P-value for this hypothesis test is nothing. ​(Round to three decimal places as​ needed.)

Identify the conclusion for this hypothesis test.

A. Reject Upper H 0. There is not sufficient evidence to warrant rejection of the claim that 51.4​% of newborn babies are boys.

B. Fail to reject Upper H 0. There is sufficient evidence to warrant rejection of the claim that 51.4​% of newborn babies are boys.

C. Fail to reject Upper H 0. There is not sufficient evidence to warrant rejection of the claim that 51.4​% of newborn babies are boys.

D. Reject Upper H 0. There is sufficient evidence to warrant rejection of the claim that 51.4​% of newborn babies are boys.

Do the results support the belief that 51.4​% of newborn babies are​ boys?

A. The results do not support the belief that 51.4​% of newborn babies are​ boys; the results merely show that there is not strong evidence against the rate of 51.4​%.

B. The results support the belief that 51.4​% of newborn babies are boys because there was no evidence to show that the belief is untrue.

C. The results support the belief that 51.4​% of newborn babies are boys because there was sufficient evidence to show that the belief is true. D. The results do not support the belief that 51.4​% of newborn babies are boys because there was sufficient evidence to show that the belief is untrue.
