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

question 10

Multiple Choice

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.

Definitions:

Total Resistance

Refers to the cumulative resistance within an electric circuit, affecting the overall current flow.

Series RC

A circuit configuration consisting of a resistor (R) and capacitor (C) connected end-to-end or in series with each other, affecting the circuit's overall impedance.

Voltage Drop

The reduction in voltage across components in an electrical circuit, caused by the impedance or resistance of the components.

Capacitive Reactances

The opposition that a capacitor presents to the flow of alternating current, due to its ability to store and release energy in its electric field.
