Assume that you manage a fund invested in risky assets. Your fund has an expected rate of return of 20% and a standard deviation of 15%. The T-bill rate is 4%. You have a client who chooses to invest 27% of her complete portfolio in your fund and the rest in T-bills (i.e., risk free). What is the standard deviation of your client's complete portfolio? Enter your answer in \% with one decimal (e.g., 8.7 not 0.087)
