Total blood volume (in ml) per body weight (in kg) is important in medical research.  For healthy adults, the red blood cell volumemean is aboutµ = 28 ml/kg with a standard deviation of4.75ml/kg.  Red blood cells volume that is too low or too high can indicate a medical problem.    Suppose he does a hypothesis test with asignificance level of 0.01.

Roger’s null hypothesis is that his blood tests are normal and that his alternative hypothesis is that something is wrong.  Symbolically, the null and hypotheses are as follows

Ho: µ = 28 ml/kg and Hi: µ ≠ 28 ml/kg

(Sampling a Normal Distribution for the Mean µ)

Assuming Roger calculates a P-value of 0.0088, does heaccept or reject the null hypothesis?
