Consider three stock funds, which we will call Stock Funds $1,2,$ and $3.$ Suppose that Stock Fund $1$ has a mean yearly return of $26\mathrm{.}00$ percent with a standard deviation of $4\mathrm{.}00$ percent; Stock Fund $2$ has a mean yearly return of $23\mathrm{.}80$ percent with a standard deviation of $16\mathrm{.}30$ percent, and Stock Fund $3$ has a mean yearly return of $11\mathrm{.}20$ percent with a standard deviation of $1\mathrm{.}70$ percent.

$($a$)$ For each fund, find an interval in which you would expect $95\mathrm{.}44$ percent of all yearly returns to fall. Assume returns are normally distributed. $($Round your answers to $2$ decimal places. Negative amounts should be indicated by a minus sign.$)$
