All human blood can be "ABO-typed" as one of O, A, B, or AB, but the distribution of the types varies a bit among groups of people. Here is the distribution of blood types for a randomly chosen person in a country. Blood type A National probability 0.43 0.12 AB ? (a) What is the national probability of type AB blood? O 0.41 (b) Maria has type B blood. She can safely receive blood transfusions from people with blood types O and B. What is the probability that a randomly chosen person from this country can donate blood to Maria?

We wish to know if the computer flips "fair coins". a) First, determine the sample size necessary to estimate the true proportion of heads with 90% confidence to within 3% of the actual proportion. Round z-critical to three decimal places. b) Generate a sample (size found above) using the following site: http://www.shodor.org/interactivate/activities/Coin/. Insert the number of tosses and under “Display Results” click on “Table”. Record the number of heads. Next, find the sample proportion of heads rounded to three decimal places. c) Use P-Value method to test the claim that the coin is unfair. Identify the null and alternative hypotheses (using correct mathematical symbols), test statistic, P-value, and conclusion.
A population proportion is 0.58. Suppose a random sample of 658 items is sampled randomly from this population. what is the probability that the sample proportion is between 0.53 and 0.56? What is the probability that the sample proportion is less than 0.49?
