According to an article in Newsweek, the natural ratio of girls to boys is 100:105 . In China, the birth ratio is 100:116 ( 46.3% girls). Suppose you don’t believe the reported figures of the percent of girls born in China. You conduct a study. In this study, you count the number of girls and boys born in 100 randomly chosen recent births. There are 42 girls and 58 boys born of the 100 . Based on your study, do you believe that the percent of girls born in China is 46.3 ? A.)What is the test statistic? Round your answer to three decimal places. (z / t ) = B.) What is the p -value? Round your answers to four decimal places. p -value = C.) Let α=0.05 . Decision: (Reject the null hypothesis / do not reject the null hypothesis) Reason for decision: ( a < p-value / a > p-value) Conclusion: There is (insufficient/ insufficient) evidence to conclude that the percentage of girls born in China is different from 46.3% .
