Extracted text: A clinical trial tests a method designed to increase the probability of conceiving a girl. In the study, 409 babies were born, and 209 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? О А. Но: р#0.5 О В. Но: р-0.5 H1: p<0.5 h1:="" p="0.5" о="" с.="" но:=""><0.5 h,:p="0.5" o="" d.="" ho:="" p=""> 0.5 H,: p = 0.5 O E. Ho: p= 0.5 H,: p>0.5 O F. Ho: p= 0.5 H,: p+0.5 b. What is the P-value? P-value = (Round to four decimal places as needed.)
