Question

Ashley and Sanjay are donating blood at a local hospital. As a standard practice, the blood
is screened for anemia (low levels of red blood cells), and the results are given to each
donor as a z score, ranging from negative scores (low amounts of red blood cells, anemic)
to positive scores (high amounts of red blood cells, not anemic). Ashley's z score is -1 while
Sanjay's z score is 0.2. Who has anemia?
a. Ashley
b. Sanjay
c. both
d. neither

Answer 1

well, who has a negative z score?

Answer 2

A negative Z score does not necessarily indicate anemia. It would have to be significantly low, P < .05,
Z < -1.96, to be considered anemic.
