Question
Chapter A1, Problem A1.16QAP
Interpretation Introduction
Interpretation:
In a NIST reference steel sample the certified percentage of nickel is 1.12% and the standard deviation related to this 0.03%. The determination of percentage produce for the nickel using new spectrometric method is − 1.10, 1.08, 1.09, 1.12 and 1.09. The indication of the bias in the method at the 95% level is to be determined.
Concept introduction:
The formula that will be used-
Here,
N = degree of freedom
s = standard deviation
t = constant
