Suppose that observations on a stock continuously compounded returns $($in percentage$)$ at the end of each of $3$ consecutive weeks are as follows:

$\backslash$table$[[$Week$,$Returns$],[1,-1\mathrm{.}11],[2,-0\mathrm{.}64],[3,-3\mathrm{.}86]]$

What is the estimated annualized volatility? Answer in percentage with two decimal digits accuracy. Example: $24\mathrm{.}57$
