During the past five years, you owned two stock that had the following annual rates of return:

Stock T: $0\mathrm{.}17$; $0\mathrm{.}09$; $-0\mathrm{.}12$; $-0\mathrm{.}07$; $0\mathrm{.}10$

Stock B: $0\mathrm{.}08$; $0\mathrm{.}05$; $-0\mathrm{.}10$; $0\mathrm{.}04$; $0\mathrm{.}02$

A$.$ Compute the arithmetic mean annual rate of

return for each stock. Round to one decimal place. Is it better to have a higher or lower arithmetic mean annual rate of return?

B$.$Compute the standard deviartion of the annual rate of return for each stock. Round to three decimal places. Which stock is more preferrable

C$.$ Compute the coefficicent of variation for each stock. Which stock is better?

D$.$ Compute the geometric mean rate of return for each stock. Round to three decimal places
