Based on economists$$ forecasts and analysis, one$-$year Treasury bill rates and liquidity premiums for the next four years are expected to be as follows:

$1$R$1=0\mathrm{.}48\%$

E$(2$r$1)=0\mathrm{.}82\%$ L$2=0\mathrm{.}06\%$

E$(3$r$1)=0\mathrm{.}92\%$ L$3=0\mathrm{.}17\%$

E$(4$r$1)=1\mathrm{.}22\%$ L$4=0\mathrm{.}18\%$

Calculate the yield to maturity for four years. $($Round your percentage answers to $2$ decimal places. $($e$.$g$.,32\mathrm{.}16))$
