A random sample of 815 births included 434 boys. Use a 0.01 significance level to test the claim that 50.6% of newborn babies are boys. Do the results support the belief that 50.6% of newborn babies are boys? O A. The results do not support the belief that 50.6% of newborn babies are boys because there was sufficient evidence to show that the belief is untrue. O B. The results support the belief that 50.6% of newborn babies are boys because there was no evidence to show that the belief is untrue. O C. The results support the belief that 50.6% of newborn babies are boys because there was sufficient evidence to show that the belief is true. O D. The results do not support the belief that 50.6% of newborn babies are boys; the results merely show that there is not strong evidence against the rate of 50.6%.
