## Elementary Technical Mathematics

The median of the data measured by the technician is $7.0036$ mm.
$7.0036$mm, $7.0035$mm, $7.0038$mm, $7.0035$mm, $7.0036$mm Arranging the data in the ascending order: $7.0035$mm, $7.0035$mm, $7.0036$mm, $7.0036$mm, $7.0038$mm. The number of measured values is$5$. Thus, the middle observation in the arranged order is the 3rd one, which is $7.0036$mm. Thus, the median of the data measured by the technician is $7.0036$ mm.
