clinical trial was conducted using a new method designed to increase the probability of conceiving a boy. As of this writing, 282 babies were born to parents using the ew method, and 244 of them were boys. Use a 0.01 significance level to test the claim that the new method is effective in increasing the likelihood that a baby will be a boy, Identify the null hypothesis, alternative hypothesis, test statisticand final conclusion that addresses the original claim. Which of the following is the hypothesis test to be conducted? O A. Ho: p=0.5 OB. Ho: p>0.5 H4: p>0.5 H:p-0.5 OC. Ho: p=0.5 H: p#0.5 OD. Ho: p<0.5 H:p=0.5 O E. Ho: p=0.5 OF. Ho: p40.5 H:p<0.5 H:p=0.5 What is the test statistic? z= 23.59 (Round to two decimal pla as needed.) What is the final conclusion? O A. There is not sufficient evidence to support the claim that the new method is effective in increasing the likelihood that a baby will be a boy. B. There is sufficient evidence to support the claim that the new method is effective in increasing the likelihood that a baby will be a boy. O C. There is sufficient evidence to warrant rejection of the claim that the new method is effective in increasing the likelihood that a baby will be a boy. O D. There is not sufficient evidence to warrant rejection of the claim that the new method is effective in increasing the likelihood that a baby will be a boy.

Question
Transcribed Image Text:clinical trial was conducted using a new method designed to increase the probability of conceiving a boy. As of this writing, 282 babies were born to parents using the
ew method, and 244 of them were boys. Use a 0.01 significance level to test the claim that the new method is effective in increasing the likelihood that a baby will be a
boy, Identify the null hypothesis, alternative hypothesis, test statisticand final conclusion that addresses the original claim.
Which of the following is the hypothesis test to be conducted?
O A. Ho: p=0.5
OB. Ho: p>0.5
H4: p>0.5
H:p-0.5
OC. Ho: p=0.5
H: p#0.5
OD. Ho: p<0.5
H:p=0.5
O E. Ho: p=0.5
OF. Ho: p40.5
H:p<0.5
H:p=0.5
What is the test statistic?
z= 23.59
(Round to two decimal pla
as needed.)
What is the final conclusion?
O A. There is not sufficient evidence to support the claim that the new method is effective in increasing the likelihood that a baby will be a boy.
B. There is sufficient evidence to support the claim that the new method is effective in increasing the likelihood that a baby will be a boy.
O C. There is sufficient evidence to warrant rejection of the claim that the new method is effective in increasing the likelihood that a baby will be a boy.
O D. There is not sufficient evidence to warrant rejection of the claim that the new method is effective in increasing the likelihood that a baby will be a boy.
