A clinical trial was conducted using a new method designed to increase the probability of conceiving a girl. As of this writing, 963 babies were born to parents using the new method, and 887 of them were girls. 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 girl. 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 normal distribution as an approximation to the binomial distribution.
What is the test statistics?
t=_ (round to two decimal places as needed.)
P-value is =_ (round to four decimal places as needed.)
