can you just write the answers please? Human blood is classified by the presence or absence of three main antigens (A, B, and Rh). When a blood specimen is typed, the presence of the A and/or B antigen is indicated by listing the letter A and/or the letter B. If neither the A nor the B antigen is present, the letter O is used.The following table gives the percent of a certain country's population having each of the eight possible blood types in the sample space. Note that the presence or absence of the Rh antigen is indicated by the symbols + or −, respectively. Blood Types A+ A− B+ B− AB+ AB− O+ O− Percent 35.7 6.3 9.5 2.5 3.2 0.8 37.4 4.6 (a) What is the probability that a person selected randomly from the population has a blood type that is type O or Rh+? (b) What is the probability that a person selected randomly from the population has a blood type that contains the A antigen?

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 64 girls and 86 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 standard deviation to four decimal places.)P' ~ What is the test statistic?

Lucky Spot? A reporter working on a story about theNew York lottery contacted one of the authors of thisbook, wanting help analyzing data to see if some ticketsales outlets were more likely to produce winners. Hisdata for each of the 966 New York lottery outlets aregraphed below; the scatterplot shows the ratio TotalPaid/TotalSales vs. TotalSales for the state’s “instant winner”games for all of 2007.The reporter thinks that by identifying the outlets withthe highest fraction of bets paid out, players might beable to increase their chances of winning. (Typically—but not always—instant winners are paid immediately(instantly) at the store at which they are purchased.However, the fact that tickets may be scratched off andthen cashed in at any outlet may account for some outletspaying out more than they take in. The few with very lowpayouts may be on interstate highways where playersmay purchase cards but then leave.)a) Explain why the plot has this funnel shape.b) Explain why the…
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% .
