Suppose we want to compare fasting serum-cholesterol
levels among recent Chinese immigrants to Ghana with typical levels
found in the general Ghanaian population. Suppose we assume
cholesterol levels in women ages 21−40 in Ghana are approximately
normally distributed with mean 190 mg/dL. It is unknown whether
cholesterol levels among recent Chinese immigrants are higher or
lower than those in the general Ghanaian population. Let’s assume
that levels among recent female Chinese immigrants are normally
distributed with unknown mean μ. Hence...

of 30. Levels above 200 need attention. Find the probability that a
teenage boy has a cholesterol level:
Greater than 200.
Less than 120.
