Throwback Question: Suppose we know that the risk of liver cancer among alcoholics without cinhosis of the liver is 22.8%. A researcher conjectures that the risk of cancer amang alcoholics with cirrhosis of the liver is higher. Suppose we sample 82 alcoholics
with cirrhosis of the liver and determine 24 have liver cancer. Use this information to answer the following:
