Question: \[{{X}_{1}},...,{{X}_{64}}\] are identically distributed independent random variables such that
\[E({{X}_{i}})=3.1\] and \[Var({{X}_{i}})=9\]. What is the standard deviation of their average?
In other words, what is the standard deviation of \[X=\] \[\frac{{{X}_{1}}+...+{{X}_{64}}}{64}\] ?
