Q2 In addition to the assumptions in the previous question , assume rindex has a of 0.05 % and a standard deviation of 1.5% . What is the expected xvalue of r What is the standard deviationxofr E [ xyz] 0.07% Var[ xyz ]=El(xyz - Er(xyz )^2]=E [(index + E- E[Pdex ])^2]=E [p(ndex- [index]+=)^2 Var[xyz ]=B^2E [index- Eindex])^2]+E [&^2]=P^2VGindex]+Var[=] Var[xyz]=12^2*15% ^2+1% ^2=0.000424
