Please run the following code

set.seed$(815)$

randomvar $=$rnorm$(1,10,3)$

mysample $=$

c$(9,1,5,2,3,6,7,5,$ NA$,5,2,2,6,7,8,9,9,1,$randomvar$)$

Now, compute the standard deviation of mysample.

Round up your answer $($e$.$g$.,3\mathrm{.}224).$ Please note that the

correct answer is specified in "range" so don't worry

about rounding errors.
