(For this question, just give me a numerical answer) Consider the following scenario analysis:

Scenario	Probability	Rate of Return (Stocks)	Rate of Return (Bonds)
Recession	0.3	-6%	14%
Normal economy	0.6	15%	8%
Boom	0.1	24%	5%

Assume a portfolio with weights of 0.60 in stocks and 0.40 in bonds.

What is the standard deviation of the portfolio?

(Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places.)
