Question $1$

The $rm$ column uses $z1$ to simulate market monthly returns with a mean $=0\mathrm{.}01$ and std $=0\mathrm{.}04.$ which of the following is true

the mean of the data under $rm$ in column $M$ is $0\mathrm{.}0100000$

the std of the data under rm in column M is $0\mathrm{.}040110$

$rm$ is calculated based on the formula $rm=$ mean $+s{d}^{***}z1$

$rs$ is calculated by adding $$L$$$3^{**}z2$ to value in answer $3$

all of the above is true
