Knowing your blood type is important not only because it determines who you can donate blood to but also who you can receive blood from. The second most common blood type in Canada is A positive and 36 percent of Canadians share this blood type. The least common blood type is AB negative and only 0.5 percent of Canadians have this blood type. Suppose a random sample of 100 Canadian donors has been chosen at random. In this sample, let X be the number of donors with A positive blood, and let Y be the number of donors with AB negativeblood.
(a) Find the mean of X.
(b) Find the variance of X.
(c) Use either the normal or the Poisson approximation, whichever is appropriate, to find the simplest estimate for the probability P(X  ≥  41).
(d) Find the mean of Y.
(e) Find the variance of Y.
(f) Use either the normal or the Poisson approximation, whichever is appropriate, to find the simplest estimate for the probability P(Y  ≥  2).

Blood type AB is found in only 3% of the population.† If 300 people are chosen at random, find the probability of the following. (Use the normal approximation. Round your answers to four decimal places.) (a) 5 or more will have this blood type (b) between 5 and 10 will have this blood type

1. Every two seconds someone in America needs blood. It is important that hospitals have the right types of quality blood to meet the patient needs. Blood donation centers help hospitals meet this demand. There are four main blood groups: A, B, AB, and O, of which O is the most common. One of the less common blood types is B+. In the United States, only 9% of the population has B+ blood type. Assume that 5 donors arrive to...

Problem 1: Relations among Useful Discrete Probability Distributions. A Bernoulli experiment consists of only one trial with two outcomes (success/failure) with probability of success p. The Bernoulli distribution is P (X = k) = pkq1-k, k=0,1 The sum of n independent Bernoulli trials forms a binomial experiment with parameters n and p. The binomial probability distribution provides a simple, easy-to-compute approximation with reasonable accuracy to hypergeometric distribution with parameters N, M and n when n/N is less than or equal...

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 43 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that σ = 7.70 ml/kg for the distribution of blood plasma. (b) What conditions...
