6) Medical : Red Blood Cell Volume Total blood volume (in ml) per body weight (in kg) is important in medical research. For healthy adults, the red blood cell mean is about y = 28 ml/kg. Red Blood cell volume that is too low or too high can indicate a medical problem. Suppose that Roger has had seven blood tests, and the results were 32 25 41 35 30 37 29 The sample mean is x 32.7 ml/kg. Let x...
