## Elementary Technical Mathematics

The mean of the data measured by the technician is $7.0036$ mm.
The measurements taken by the technician are, $7.0036$mm, $7.0035$mm, $7.0038$mm, $7.0035$mm, $7.0036$mm The sum of the all measured values is \begin{align} & \text{sum of all values }=7.0036+7.0035+7.0038+7.0035+7.0036 \\ & =35.018 \end{align} The number of measured values is $5$. Thus, the mean of the data is \begin{align} & \text{Mean}=\frac{\text{Sum of the all measured values}}{\text{Number of the measured values}} \\ & =\frac{35.018}{5} \\ & =7.0036 \end{align}
