Hepatic Disease Suppose we observe 84 alcoholics with cirrhosis of the liver, of whom 29 have hepatomas-that is, liver-cell carci- noma. Suppose we know, based on a large sample, that the risk of hepatoma among alcoholics without cirrhosis of the liver is 24%. 5.50 What is the probability that we observe exactly 29 alcoholics with cirrhosis of the liver who have hepatomas if the true rate of hepatoma among alcoholics (with or without cirrhosis of the liver) is .24?

Suppose we observe 84 alcoholics with cirrhosis of the
liver, of whom 29 have hepatomas-that is, liver-cell carci-
noma. Suppose we know, based on a large sample, that the
risk of hepatoma among alcoholics without cirrhosis of the
liver is 24%.
5.50 What is the probability that we observe exactly 29
alcoholics with cirrhosis of the liver who have hepatomas if
the true rate of hepatoma among alcoholics (with or without
cirrhosis of the liver) is .24?
5.51 What is the probability of observing at least 29 hepa-
tomas among the 84 alcoholics with cirrhosis of the liver
under the assumptions in Problem 5.50?
5.52 What is the smallest number of hepatomas that would
have to be observed among the alcoholics with cirrhosis of
the liver for the hepatoma experience in this group to differ
from the hepatoma experience among alcoholics without
cirrhosis of the liver? (Hint: Use a 5% probability of getting
a result at least as extreme to denote differences between
the hepatoma experiences of the two groups.)
