$($b$)$ A batch of capacitors using the dimensions in part $($a$)$ii was manufactured. A

technician measured the capacitance values for a sample of $10$ of the capacitors

and recorded them in a table.

Capacitance value $($pF$)$

$2\mathrm{.}011\mathrm{.}982\mathrm{.}022\mathrm{.}011\mathrm{.}961\mathrm{.}982\mathrm{.}032\mathrm{.}011\mathrm{.}962\mathrm{.}02$

$($i$)$ Determine the median value of capacitance for the sample.

$($ii$)$ Calculate the mean value of capacitance for the sample.
