Hypothesis testing for red blood cell volume

Reference no: EM13111682

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 volume mean is about = 28ml/kg. (Reference: Laboratory and Diagnostic Tests F. Fischbach). Red Blood cell volume that is too low or too high can indicate a medical problem (see reference. Suppose Roger has had seven blood tests and the red blood cell volumes were

32 25 41 35 30 37 29

The mean is xbar 32.7 ml/kg. Let x be a random variable that represents Roger's red blood cell volume. Assume that x has a normal distribution and that = 4.75. Do the data indicate that Rogers red blood cell volume is different (either way) from = 28 ml/kg? Use 0.01 level of significance.
