Use the table for the question$($s$)$ below.

Consider the following realized annual returns:

Suppose that you want to use the $10-$year historical average return on the Index to forecast the expected future return on the Index. The $95\%$ confidence interval for your

estimate of the expect return is closest to:

$6\mathrm{.}8\%$ to $10\mathrm{.}7\%.$

$4\mathrm{.}9\%$ to $12\mathrm{.}7\%.$

$-9\mathrm{.}6\%$ to $27\mathrm{.}3\%.$

$-3\mathrm{.}5\%$ to $21\mathrm{.}1\%.$
