You are creating a moving range chart $(x-MR)$ with a $3-$period moving range. Using the data below, what is the value of the third data point on the $x-MR$ chart? $($Round to three decimal places.$)$

$\backslash$table$[[$Period $1,\mathrm{.}012],[$Period $2,\mathrm{.}017],[$Period $3,\mathrm{.}023],[$Period $4,\mathrm{.}01],[$Period $5,\mathrm{.}025],[$Period $6,\mathrm{.}02],[$Period $7,\mathrm{.}01],[$Period $8,\mathrm{.}018],[$Period $9,\mathrm{.}022],[$Period $10,\mathrm{.}025]]$

$\mathrm{.}023$

$\mathrm{.}017$

$\mathrm{.}019$

Answer $\mathrm{.}015$ is wrong
