how would you draw the CAL or tangent line on the graph given that the risk free rate is 3%

Correlation coefficient of A,B is 0.30. The risk-free rate is 3%. Fill in the following table: (12 points) Draw the efficient frontier and tangent line (risk-free point of origin) in mean-standard deviation space (put returns on the Y axis and risk on the X axis). (8 points)
