The premium would be 5%
If a portfolio had a return of 11 the risk-free asset return was 6, and the standard deviation of the portfolios excess returns was 25 the premium would be 5%
Portfolio return = 11%
Risk free rate = 6%
Risk premium = Portfolio return - Risk free rate
= 11% - 6% =5%
So, the premium would be 5%
