Question $9(1$ point$)$

A distance $AB$ is observed repeatedly using the same equipment and procedures, and the results, in meters, are listed here: $59\mathrm{.}366,59\mathrm{.}697,$

$59\mathrm{.}209,59\mathrm{.}819,59\mathrm{.}144.$ Calculate the percentage error, Ep$,$ of the distance's most probable length at the $95\%$ confidence level. Do not report

the units as part of your answer, just the numeric value to $4$ decimals assuming, also, the plus$/$minus of the uncertainty. For clarity, this is the

$\frac{+}{-}$ value that, when added to the most probable value, determines the $95\%$ confidence level range.
