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. 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. D. There is sufficient evidence to support the claim that the new method
A clinical trial was conducted using a new method designed to increase the probability of conceiving a boy. As of this writing, 301 babies were born to parents using the new method, and 245 of them were boys. Use a 0.05 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 statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method and the

Part 2
What is the test statistic?
z=enter your response here
(Round to two decimal places as needed.)
Part 3
What is the P-value?
P-value=enter your response here
(Round to four decimal places as needed.)
Part 4
What is the conclusion on the null hypothesis?
A.
Reject the null hypothesis because the P-value is less than or equal to the significance level, α.
B.
Fail to reject the null hypothesis because the P-value is greater than the significance level, α.
C.
Reject the null hypothesis because the P-value is greater than the significance level, α.
D.
Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, α.
Part 5
What is the final conclusion?
A.
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.
B.
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.
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.
D.
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.
