A Clinical Laboratory Scientist Performs 30 Replicate Hemoglobin Determinations on a Single

A clinical laboratory scientist performs 30 replicate hemoglobin determinations on a single blood sample.When statistics are used to determine the precision of the method,the mean is 13.8 g/dL and 1 SD is 0.1 g/dL.This means that 95.5% of the results on this specimen lie

A) between 13.4 and 14.2 g/dL.
B) between 13.6 and 14.0 g/dL.
C) between 13.5 and 14.1 g/dL.
D) between 13.7 and 13.9 g/dL.
