Question
Transcribed Image Text:A random sample of 855 births included 429 boys. Use a 0.01 significance level to test the claim that 50.7% of newborn babies are boys. Do the results support the belief that 50.7%
of newborn babies are boys?
Identify the null and alternative hypotheses for this test. Choose the correct answer below.
O A. Ho: p=0.507
H₁: p<0.507
O B. Ho: p=0.507
H₂₁: p0.507
O C. Ho: p=0.507
H₁: p > 0.507
O D. Ho: p*0.507
H₁: p=0.507
Identify the test statistic for this hypothesis test.
The test statistic for this hypothesis test is
(Round to two decimal places as needed.)
Identify the P-value for this hypothesis test.
Transcribed Image Text:The P-value for this hypothesis test is.
(Round to three decimal places as needed.)
Identify the conclusion for this hypothesis test.
O A. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that 50.7% of newborn babies are boys.
O B. Reject Ho. There is sufficient evidence to warrant rejection of the claim that 50.7% of newborn babies are boys.
O C. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the claim that 50.7% of newborn babies are boys.
O D. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that 50.7% of newborn babies are boys.
Do the results support the belief that 50.7% of newborn babies are boys?
O A. The results do not support the belief that 50.7% of newborn babies are boys; the results merely show that there is not strong evidence against the rate of 50.7%.
O B. The results support the belief that 50.7% of newborn babies are boys because there was no evidence to show that the belief is untrue.
O C.
The results do not support the belief that 50.7% of newborn babies are boys because there was sufficient evidence to show that the belief is untrue.
O D. The results support the belief that 50.7% of newborn babies are boys because there was sufficient evidence to show that the belief is true.
