The value of each individual question on your exam is worth $5$x more toward your course grade than this question. I highly recommend that you use this as an opportunity to practice these calculations.

Suppose that an investment has yielded the following historical annual returns for the past $5$ years:

Year $1=18\%$

Year $2=-14\%$

Year $3=13\%$

Year $4=11\%$

Year $5=9\%$

Express your answers to the following questions in percentage terms $($eg$.46\mathrm{.}7\%)$ and round according to the instructions.

What is the arithmetic average annual return for the past $5$ years? Blank $1.$ Fill in the blank, read surrounding text.

$\%($Round your answer to $1$ decimal place$)$

What is the geometric average rate of return for the past $5$ years $($CAGR$)?$ Blank $2.$ Fill in the blank, read surrounding text.

$\%($Round your answer to $2$ decimal places$).$

What is the standard deviation in returns for the past $5$ years? Blank $3.$ Fill in the blank, read surrounding text.

$\%($Round your answer to $1$ decimal place$).$
