You observe a portfolio for five years and determine that its average return is $12\mathrm{.}6\%$ and the standard deviation of its

returns in $19\mathrm{.}8\%.$ Would a $30\%$ loss next year be outside the $95\%$ confidence interval for this portfolio?

The low end of the $95\%$ prediction interval is

$\%.($Enter your response as a percent rounded to one decimal place.$)$

A$.$ Yes, you can be confident that the portfolio will not lose more than $30\%$ of its value next year. This is because

the low end of the prediction interval is greater than $-30\%.$

B$.$ No$,$ you cannot be confident that the portfolio will not lose more than $30\%$ of its value next year. This is because

the low end of the prediction interval is greater than $-30\%.$

C$.$ Yes, you can be confident that the portfolio will not lose more than $30\%$ of its value next year. This is because

the low end of the prediction interval is less than $-30\%.$

D$.$ No$,$ you cannot be confident that the portfolio will not lose more than $30\%$ of its value next year. This is because

the low end of the prediction interval is less than $-30\%.$
