Problem $13.($Uniform Random Numbers$)$ Write a program called

stats.py that accepts $a($int$)$ and $b($int$)$ as command$-$

line arguments, generates three random floats $,$ and $($:$x_3\},$ each from the interval $[a,b),$ computes their mean $=$

$\frac{x_1+x_2+x_3}{3},$ variance var$=\frac{(x_1-{)}^2+(x_2-{)}^2+(x_3-{)}^2}{3},$ and standard deviation $=\sqrt[\phantom{2}]{\text{v}\text{a}\text{r}},$ and writes those

values to standard output, separated by a space.
