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% .

The director of library services at a college did a survey of types of books (by subject) in the circulation library- Then she used library records to take a random sample of 888 books checked out last term and classified the books in the sample by subject. The results are shown below. Percent of Books on Subject in Circulation Library on This Subject 32% Number of Books in Sample on This Subject 265 Subject Area Business Humanities 25% 20% 226 Natural Science Social Science 224 15% 104 All other subjects 69 Using a 5% level of significance, test the daim that the subject distribution of books in the library fits the distribution of books checked out by students. (a) What is the level of significance? State the null and alternate hypotheses. O Hg: The distributions are the same. H: The distributions are the same. O Hg: The distributions are different. H: The distributions are different. O Hg: The distributions are different. H: The distributions are the same. O Hg: The distributions…

In 1950, an organization surveyed 1100 adults and asked, "Are you a total abstainer from, or do you on occasion consume, alcoholic beverages?" Of the 1100 adults surveyed, 374 indicated that they were total abstainers. In a recent survey, the same question was asked of 1100 adults and 330 indicated that they were total abstainers. Complete parts (a) and (b) below. (a) Determine the sample proportion for each sample. The proportions of the adults who took the 1950 survey and the recent survey who were total abstainers are respectively. (Round to three decimal places as needed.) 1559 and
