Total plasma volume is important in determining the required plasma component in blood replacement theory for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that sample of 61 male firefighters are tested and that they have a plasma volume sample mean of x = 39.5 ml/kg (milliliters of plasma per kilogram body weight). Assume that o = 7.50 ml/kg for the distribution of blood plasma. Find the margin of error for 98% confidence level of the population mean blood plasma volume in male firefighters. Round your answer to two decimal places.
