A clinical trial was conducted using a new method designed to increase the probability of conceiving a boy. As of this writing, 291 babies were born to parents using the new method, and 226 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...

A clinical trial tests a method designed to increase the
probability of conceiving a girl. In the study 400 babies were
born, and 340 of them were girls. Use the sample data to construct
a 99% confidence interval estimate of the percentage of girls
born. Based on the result, does the method appear to be
effective?
