Assume 40% of us have Group O blood. A hospital is conducting a blood drive because its supply of Group O blood is low, and it needs at least 158 donors of Group O blood. If 393 volunteers donate blood, estimate the probability that the number with Group O blood is at least 158. Is the pool of 393 volunteers likely to be sufficient? (a) P(Xgreater than or equals158)equals nothing (Round to four decimal places as needed.)

Ms. Lewis is in urgent need of a blood transfusion. She has type A blood. The blood bank is out of tye A blood and has only type B blood. Ms. Lesis asks the doctor is she can use the B blood. Would this transfusion cause an agglutination reaction? Defend your answer, discussing the antigens and/pr antibodies present in the donor and recipient blood.

People with type O‑negative blood are known as universal donors. That is, a patient with any blood type can receive a transfusion of O‑negative blood. Approximately 7.6% of the American population has O‑negative blood. Suppose 8 people appear at random to give blood. Let A represent the event where at least one of the 8 people has type O‑negative blood. Calculate P(A), the probability that at least one of the 8 people has type O‑negative blood. Please round your answer...

A small village, which has no hospital nearby, is served by three mobile units coming from three centers A, B, and C. These units also serve many other villages in the region. The units pass through the village several times a day and they appear on the average frequently. What is the probability that a waiting patient will be served by the unit coming from center B? Now, suppose unit A can serve only adult males, unit B can serve...

. 40% of the population has type A blood. a. If 9 people are selected at random, what is the probability that less than four of them have type A blood. b. If 90 donors come to give blood one day, what is the probability that less than 40 of them have Type A blood (using the normal approximation)? Explain why this is higher or lower than the answer in part (a). c. If 15 people give blood one day,...

Approximately 9% of the US population has type 2 diabetes. A fasting blood glucose test is one option to test for type 2 diabetes. Using this test, the probability that a person tests positive, given that they have diabetes is 0.6. What is the value of the intersect of diabetes and test result positive? P(diabetes ∩ testpositive) =

Problem 3. Consider the following blood inventory problem facing a hospital. There is need for a rare blood type, namely, type AB, Rh negative blood. The demand D (in pints) over any 3-day period is given by Note that the expected demand is 1 pint, since E(D)-04(1) +0.15(2) +0.1(3)-1. Sup. pose that there are 3 days between deliveries. The hospital proposes a policy of receiving 1 pint at each delivery and using the oldest blood first. If more blood is...

A random blood bank has either type A, type B, or type O with probabilities 0.10, 0.35, 0.25. There is a 0.30 probability that the patient will need type AB. a) What is the probability that among 10 candidates needing blood, 5 need AB, 3 need A, and at least one needs O? b) What is the probability that the 6th candidate approaching for blood is the 3rd one needing B?

This question has two parts. Part 1) Assume that for an ad campaign to be successful, at least 76% of those seeing a television commercial must be able to recall the name of the company featured in the commercial one hour after viewing the commercial. Before distributing an ad campaign nationally, an advertising company plans to show the commercial to a random sample of 24 people. It will also show the same people two additional commercials for different products or...
