You invest in an investment fund, where the random annual return will be 1% with probability 0.15; 4% with probability 0.65; and 5% with probability 0.2. The annual returns in different years are independent and identically distributed. For a time-O investment of $260, calculate the standard deviation of the time-11 accumulated value.
