Consider this normal distribution graph and the information below for

the next two questions. $($Hint: These questions illustrate how you

might see numerical Normal Distribution questions on an exam$).$

You have analyzed $30$ years of historical, annual returns of the iShares

Nasdaq Biotechnology ETF $($ticker IBB$).$ You found the average return

$=15\%$ and the standard deviation of returns $=20\%.$ Based on this

analysis, you plan to model future IBB returns $($for better or worse$)$ as

normally distributed, with mu $($average$)=15\%$ and sigma $($standard

$($deviation$)=20\%.$

Question $6$

What is the probability that, in any given future year, IBB will lose $25\%$

or more of its value? Round your answer to three decimal places.

Question $7$

What is closest to the probability that, in any given future year, IBB's

return will be $35\%?$
