A clinical trial tests a method designed to increase the probability of conceiving a girl. In the study, 407 babies were born, and 216 of them were girls. Use the sample data with a 0.01 significance level to test the claim that with this method, the probability of a baby being a girl is greater than 0.5. Use this information to answer the following questions. a. Which of the following is the hypothesis test to be conducted? O A. Ho:...
