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 and physical activity of an individual. Suppose that a random sample of 42 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that σ = 8.00 ml/kg for the distribution of blood plasma. (a)margin of error (b)What conditions are necessary for your calculations? (Select all that apply.) σ is known the distribution of weights is normal σ is unknown n is large the distribution of weights is uniform
