QUESTION $01(05$ points$)-$ Coefficient of Variation $($CV$)$

We need to compare volatility of multiple assets. As the assets have different variation ranges, e$.$g$.$ a big stock versus a penny stock, it is useful to look at the coefficient of variation $($CV$),$ not the standard deviation, as a measure of volatility. Inspired by real$-$life companies, we have the following hypothetical population data:

$\backslash$table$[[,$Asset A$,$Asset B$,$Asset C$],[$Mean $($$$),420\mathrm{.}16,12\mathrm{.}20,170\mathrm{.}08],[$Standard deviation $($$$),16\mathrm{.}99,2\mathrm{.}09,12\mathrm{.}78]]$

$($a$)[1]$ Give an equation for the coefficient of variation in percentage terms.

$($b$)[3]$ Find volatility of the three assets. Use two decimals for percentages, e$.$g$.23\mathrm{.}76\%.$

$($c$)[1]$ Which asset is the least volatile? Which asset is the most volatile?
