Chapter A1, Problem A1.13QAP

Interpretation Introduction

Interpretation:

First calculate the mean and standard deviation for each of the six data sets that are given and after that calculate the $95\%$ confidence interval for each set of data.

Concept introduction:

$95\%$ of confidence interval can be calculated as follows when $s$ is a good estimate of $\sigma$ - $CI=\overline{x}\pm \frac{z\sigma }{\sqrt{N}}$

Where

$\overline{x}=$ Mean.

$z=$ Function of quantity.

$N=$ Degree of freedom

$CI=$ Confidence interval.
