Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health andphysical activity of an individual. Suppose that a random sample of 45 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogrambody weight).

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. Over a period of months, and adult male patient has taken 13 blood test for uric acid. The main concentration was X=5.41 mg/dl. The distribution of uric acid and healthy adult meals can be assumed to be normal, with o=1.81 mg/dl. find a 95% confidence interval for the population mean concentration of uric acid in the patient's blood.
