A clinical trial tests a method designed to increase the probability of conceiving a girl. In the study 310 babies were born, and 279 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? < p< (Round to three decimal places as needed.) Does the method appear to be effective? O No, the proportion of girls is not significantly different from 0.5. O Yes, the proportion of girls is significantly different from 0.5.
