For the following box with 15 draws, what code calculates the standard error for the sum of the draws? $b o x=c(0,1,2,3,9)$ $\operatorname(sqrt}(15)^{*} \operatorname(sqrt}\left( ight. $ mean( $\left.\left. (\text { box }-\operatorname{mean}(\text { box })^{\wedge} 2 ight) ight) $ $\operatornamesart}(5) * \operatornamesart}\left( me a nileft((bo x-loperatorname{mean} (loperatorname {box})^{\wedge} ight) ight) $ $\operatorname {sqrt} (15)^{*} \operatorname(sqrt}\left( ight. $ mean $\left. (\text { (box }-\text { mean(box })^{\wedge} 2 ight) $ $\operatornamesqrt(15)^{*} \operatorname(sqrt}\left(\operatorname (mean}\left(\left (box-operatorname (mean}(box)^{\wedge} 2 ight) ight) ight. $ CS.PC.003
