The Genetics and IVF Institute conducted a clinical trial of XSORT method designed to increase the probability of conceiving a girl. 325 babies were born to parents using the XSORT method, and 295 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. Does the method appear to work? Solution H0: p1=p2 HA: p1?p2 In this problem p1 will refer to girls. Test statistic = z = 3.01 P-value = 0.003 Conclusion: Since the P-value is smaller than alpha, we reject the hypothesis that the two population proportions are the same. The statistical evidence suggests that the XSORT (girl) methodology is superior to the xSORT (boy) methodology. NOTE THAT WE DIDN.
