The gunner on the assault boat SS Minnie Chang fires six missiles at an attacking plane. Each has a 20% chance of being on target. If two or more shells find their mark, the plane will crash. At the same time, the pilot of the plane fires 10 surface-to-air rockets, each of which has a 0.05 chance of sinking the boat. If you want to live, would you rather be on the plane or on the boat?

Suppose you are tested to see if you have a rare disease. Assume that if you have the disease, your test will always come back positive, but if you do not have the disease, there is still a 0.001 chance that you will test positive. In reality, only 1 of 10,000 people have the disease. Your doctor calls and says that you have tested positive. He is sorry but there is a 99.9% (120.001) chance that you have the disease. Is he correct? What is the actual probability that you have the disease?

Some electronic devices are better used than new: The failure rate is higher when they are new      than when they are six months old. For example,   53.40% of the personal music players of a particular  brand have a flaw. If the player has the flaw, it dies in the first six months. If it does not   have this flaw, then only  6.600% fail in the first six months. Yours died after you had   it for three months. What are the chances that  it has this flaw?

The Literary Digest was an American magazine that ran from 1890–1938.  The magazine was famous for correctly predicting presidential winners since 1916 based on poll results.  In 1936, however, it erroneously predicted that Alfred Landon would defeat Franklin Delano Roosevelt.  This fiasco ultimately resulted in the magazine going out of business.   The reason for The Literary Digest’s incorrect results has been studied throughout the years and is a famous example in statistics classes.  One reason that researchers have found for the faulty results is that even though the magazine polled ten million people, the return rate of the surveys was around 23%.  What type of bias is this?     voluntary response bias     non-response bias     self-interest study     loaded questions     sampling bias     perceived lack of anonymity     response bias
