Use the following information to solve problems & through 14 Human blood is grouped into four types: A. B. AB and O. The percent of all Americans with each type of blood are as follows: 0: 43%, A: 40%% B: 12% and AB 5% At a recent blood drive, the number of domore having different blood types are shown below 0 AB 60 65 15 10 8. The expected value (based on the information about the blood types for all Americans) of people having O type of blood in the blood drive sample is: a. 60 b. 64.5 c. 67 9. The expected value (based on the information about the blood types for all Americans) of people having A type of blood in the blood drive sample is: a. 60 b. 65 c. 67 10. The expected value (based on the information about the blood types for all Americans) of people having B type of blood in the blood drive sample is: a. 10 b. 15 c. 18 11. The expected value (based on the information about the blood types for all Americans) of people having AB type of blood in the blood drive sample is a. 7.5 b. 10 c 15 12. The standardized test statistic value (calculated by comparing the four observed values of the different blood types from the blood-drive sample with the comesponding four expected values based on the percentages for all Americans) is: 1. 1.06 b. 2.06 C 3.06 13. The probability value of the event that the standardized test statistic would aswume a value as large as that calculated in question 12 is: a 0.36 b. 0.46 C. 0.56 14. By comparing the probability value calculated in question 13 to a $% level of significance in a hypothesis test, we can state thet . There is no difference between the proportions of people having different blood types in the blood-drive sample and the proportions of all Americany having different blood types b. There is a positive difference between that the proportions of people having different blood types in the blood-drive sample and the proportions of all Americans having different blood types C. There is a negative difference between the proportions of people having different blood types in the blood-drive sample and the proportions of all Americans having different blood types
