Mean of two portfolios: Standard deviation of two portfolios if r1,2=0.30 : Standard deviation of two portfolios if r1,2=0.80 : Choose the correct risk-return graph. r1.2=0.30 B: r1.2=0.80 Explain the results. The negative correlation coefficient - Select- risk without sacrificing return. E(R1)=0.13E(R2)=0.16E(1)=0.11E(2)=0.20w1=0.3w2=0.7 decimal places.
