Chapter A1, Problem A1.18QAP

Interpretation Introduction

Interpretation:

The presence of the systematic error in the analysis at the 95% confidence interval is to be determined.

Concept introduction:

The confidence interval can be calculated as follows:

$CI,\mu =\overline{x}\pm \frac{ts}{\sqrt{N}}$

Where,

N = degree of freedom

$\mu$ = confidence interval

$\overline{x}$ = mean

s = standard deviation

t = constant

Or,

$t_{calc}=\left|\frac{\overline{x}-{\mu }_0}{s/\sqrt{N}}\right|$

Null hypothesis-

$H_0={\mu }_0$
