Let P be the set of all people, dead or alive. Consider the function f: P\longrightarrow P where, if x is a person in P, then f(x) is the biological father of x. In order to make this a well-defined function, we will assume that everyone has one and only one biological father. Check all of the following statements that apply.

E. The function $f$ is not 1-1 because there are some people who do not have children.

F. The function $f$ is onto because everyone has a father.

G. The function $f$ is onto because everyone has only one father.

H. The function $f$ is not onto because not every person is a father.

I. The function $f$ is not onto because two people could have the same father.

J. None of the above statements apply.

Of all people in one population, 21% have high blood pressure and 36% are overweight. In addition, 42% of people who are overweight also have high blood pressure. Let H represent the event that a person has high blood pressure, and O represent the event that a person is overweight. In each part of this question, you must first express each probability in terms of the events H and O and justify any computation through the use of a formula....

It the 1980s, it was generally believed that congenital abnormalities affected about 8 % of a large nation's children. Some people believe that the increase in the number of chemicals in the environment has led to an increase in the incidence of abnormalities. A recent study examined 374 randomly selected children and found that 47 of them showed signs of an abnormality. Is this strong evidence that the risk has increased?(Consider a P-value of around 5 % to represent reasonable...
