Transcribed Image 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: р<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.)
