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-

CI,μ=x¯±tsN

Here,

N = degree of freedom

μ = confidence interval

x¯ = mean

s = standard deviation

t = constant
