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

Year Stock T Stock B

$10\mathrm{.}200\mathrm{.}08$

$20\mathrm{.}090\mathrm{.}02$

$3-0\mathrm{.}09-0\mathrm{.}05$

$4-0\mathrm{.}080\mathrm{.}01$

$50\mathrm{.}170\mathrm{.}05$

Compute the arithmetic mean annual rate of return for each stock. Round your answers to one decimal place.

Stock T:

$\%$

Stock B:

$\%$

Which stock is most desirable by this measure?

$-$Select$-$

is more desirable because the arithmetic mean annual rate of return is

$-$Select$-$

Compute the standard deviation of the annual rate of return for each stock. $($Use Chapter $1$ Appendix if necessary.$)$ Do not round intermediate calculations. Round your answers to three decimal places. Answer with the population standard deviation.

Stock T:

$\%$

Stock B:

$\%$

By this measure, which is the preferable stock?
