Question

Blood pressure Diastolic blood pressure in adults is normally
|distributed with µ = 80 mm Hg and o = 12 mm Hg. In a ran-
dom sample of 300 adults, how many would be expected to have a
diastolic blood pressure below 70 mm Hg?

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 50 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 ? = 7.20 ml/kg for the distribution of blood plasma.
