Q4. Human blood is grouped into four types: A, B, AB & O. Type O blood can be transfused to anyone (the universal donor) while people with Type AB blood can receive any blood type (the universal recipient). A country is recruiting soldiers but unsuccessful applicants accuse there exists discrimination on their blood type—too many Type A & B applicants are rejected while too many Type O & AB applicants are accepted. Use goodness-of-fit test, test whether the number of recruited soldiers in each blood type are different from the country’s national proportion significantly at the level of significance of 5%.

Blood type	PROPORTION IN THE COUNTRY	THE NUMBER OF RECRUITED SOLDIERS
A	40%	210
B	12%	100
AB	5%	120
O	43%	570

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: O: 43%, A: 40% B: 12% and AB 5%. At a recent blood drive, the number of donors having different blood types are shown below: O A B AB 60 65 15 10 1. The total sample size in this blood drive is: a. 125 b. 140 c. 150 2. The expected value (based on...

Human blood is largely divided in to four blood groups (A, B, AB, and O) and also (separately) into Rh-positive and Rh-negative. (There are also some very rare blood groupings, such as Mumbai, Lutheran, Kell, and Kipp.) This is very important in medicine, since a person may die or suffer serious harm if they receive a transfusion from an incompatible donor. According to the Stanford University School of Medicine Blood Center, the distribution of blood groups/types in the United States...

Your blood belongs to one of four genetically determined types: O, A, B, or AB. A bulletin issued by a large blood bank claims that these four blood types are distributed in the U.S. population according to the following proportions: 0.44 are type O, 0.41 are type A, 0.10 are type B, and 0.05 are type AB. Let’s treat this claim as a null hypothesis to be test with a random sample of 100 students from a large university. The...

A mother has blood type AB and a father has blood type O and they have a child together. What is the probability that their child will have O blood type like the father? 8. If blood is needed to be given to the mother and AB blood type is not available, what other blood types can the mother receive (not considering Rh factor)? Explain your answer. Explain why a person with AO genotype has the same phenotype (blood type...

In a sample of 1617 Spanish Basques, the numbers of A, B, O, and AB blood types observed were 724, 110, 763, and 20, respectively. These blood groups are due to three alleles, I A , I B , and I O , with I A I A and I A I O having blood group A; with I B I B and I B I O having blood group B; with with I A I B having blood group...
