2. Diagnostic Tests: Uric Acid Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of illness such as
gout, leukemia, or lymphoma (Reference: Manual of Laboratory and Diagnostic
Tests, F. Fischbach). Over a period of months, an adult male patient has taken eight
blood tests for uric acid. The mean concentration was x = 5.35 mg/dl. The distri-
bution of uric acid in healthy adult males can be assumed to be normal with
o = 1.85 mg/dl.
(a) Find a 95% confidence interval for the population mean concentration of uric
acid in this patient's blood. What is the margin of error?
(b) What conditions are necessary
for
your
calculations?
(c) Give a brief interpretation of your results in the context of this problem.
