Identify the conclusion for this hypothesis test.
O A. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that 51.1% of newborn babies are boys.
O B. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the claim that 51.1% of newborn babies are boys.
O C. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that 51.1% of newborn babies are boys.
O D. Reject Ho. There is sufficient evidence to warrant rejection of the claim that 51.1% of newborn babies are boys.
Do the results support the belief that 51.1% of newborn babies are boys?
O A. The results do not support the belief that 51.1% of newborn babies are boys; the results merely show that there is not strong evidence against the rate of 51.1%.
O B. The results do not support the belief that 51.1% of newborn babies are boys because there was sufficient evidence to show that the belief is untrue.
O C. The results support the belief that 51.1% of newborn babies are boys because there was no evidence to show that the belief is untrue.
O D.
