Total blood volume (in ml) per body weight (in kg) is important in medical research. For healthy adults, the red blood cell volume mean is about ? = 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 red blood cell volumes were as follows. 32 25 42 34 32 39 31 I need help with sketching the distribution (d) and (e)

How does the variance of the sample mean compare to the variance of the population? Multiple Choice It is larger and therefore suggests that averages have more variation than individual observations. It is larger and therefore suggests that averages have less variation than individual observations.
