A clinical trial tests a method designed to increase the probability of conceiving a girl. In the study

365 babies were born, and 292 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?

At 99 % CI for proportion is ( 0.75 , 0.85 )

Therefore, since the confidence interval technically contains 0.75 - 0..80, which is the more than 50/50 chance of having a girl.so the methods appear to be effective.
