Let’s say that about 38% of the population has O+ blood type. If we had 217 volunteers come in to donate blood, about how many would we expect to have O+ blood? Say we needed to get 100 people with O+ blood to meet current demand. What is the probability that we will reach that goal with the 217 that came? How could we increase the probability of getting at least 100 with O+ to donate?

Answer #1

Number of expected people to have O+ blood is

The probability that we will reach that goal with the 217 that came is

Excel function used to find the above probability is "=BINOMDIST(100,217,0.38,FALSE)"

To increase the probability of getting at least 100 with O+ to donate we need to increase the sample size.

At a particular blood bank, 45% of donors have type O blood. On a certain day, the blood bank needed 4 donors with type O blood and it took 12 donors to meet their quota. This surprised the director since it usually doesn’t take that many donors to find 4 with type O blood. Could this have occurred by random chance or were people with type O blood particularly stingy on that day? Design and conduct a simulation (do 10...
