(D) Metabolism - Correct Answer - (C) Proliferation
What is the percent error of the dose calibrator reading if a 4 ml
reference volume (expected) of the geometry test reads 2.8 mCi, and the
actual reading obtained in 10 ml volume is 2.5 mCi?
(A) 12%
(B) 10.7%
(C) −10.7%
(D) −12 % - Correct Answer - (B) 10.7%
The given volume is additional information and must be disregarded,
since the percent error formula does not utilize it.
