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: C I , μ = x ¯ ± t s N Where, N = degree of freedom μ = confidence interval x ¯ = mean s = standard deviation t = constant Or, t c a l c = | x ¯ − μ 0 s / N | Null hypothesis- H 0 = μ 0

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,μ=x¯±tsN

Where,

N = degree of freedom

μ = confidence interval

x¯ = mean

s = standard deviation

t = constant

Or,

tcalc=|x¯μ0s/N|

Null hypothesis-

H0=μ0
