3) 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 by F. Fischbach). Over a period of months, an adult male patient has taken eight blood tests for uric acid. The mean concentration was x = The distribution of uric acid in healthy adult males can be assumed to be normal with 5.35 mg/dl. 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? d) Find the sample size necessary for a 95% confidence level with maximal margin of error E = 1.10 for the mean concentration of uric acid in this patient's blood.
