The Genetics-ABC Research Centre is doing a research on the effect of WXYZ method which is designed to increase the probability of conceiving a (baby) girl. Using this methos 305 babies were born to the parents using WXYZ method, and 254 of them are baby girls. What is the proportion of baby girls born to the parents using WXYZ method? What is the sampling distribution of the proportion of the baby girls born to the parents using WXYZ method? Why? ) What is the standard error of the sample proportion of the baby girls born to the parents who used WXYZ methods? Use this sample data to construct a 99% confidence interval of the proportion of baby girls born to the parents using WXYZ method. What is the margin of error (MOE)? What are the lower limit and upper limit of the confidence interval MOE lower limit upper limit Based on the results in the part e, does WXYZ method appear to be effective? Why or why not
