So How do I calculate the p value? Also I'm not quite sure how to do the confidence table According to an article in Newsweek
So How do I calculate the p value? Also I'm not quite sure how to do the confidence table
According to an article in Newsweek, the natural ratio of girls to boys is 100:105. In China, the birth ratio is 100:114 (46.7% 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 150 randomly chosen recent births. There are 63 girls and 87 boys born of the 150. Based on your study, do you believe that the percent of girls born in China is 46.7? Conduct a hypothesis test at the 5% level. Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)
State the distribution to use for the test. (Round your answers to four decimal places.) P' ~ N 0.467 0.0407 Part (e) What is the test statistic? (If using the z distribution round your answers to two decimal places, and if using the t distribution round your answers to three decimal places.) Z -1.15 Part (f) What is the p-value? (Round your answer to four decimal places.) 0. 1251 XConstruct a 95% confidence interval for the true proportion. Sketch the graph of the situation. Label the point estimate and the lower and upper bounds of the confidence interval. (Round your answers to four decimal places.) 95% C.I. 0.467 XStep by Step Solution
