3. According to an article in Newsweek, the natural ratio of girls to boys is 100:105. In China, the E ratio is 100:114 (46.7% girls). Suppose you don't believe the reported figures of the percent of girls in China. You conduct a study. In this study, you count the number of girls and boys born in 150 randomly chosen recent births. There are 64 girls and 86 boys born of the 150. Based on your study you believe that the percent of girls born in China is 46.7? Conduct a hypothesis test at the 5% leve a. State the distribution to use for the test. (Round your answers to four decimal places.) P'~N (467, )
