Consider the data provided in the table below for a portfolio of assets A and B. The portfolio weights and variances are given in the table. The variances are expressed in decimal form. For example, if the standard deviation is 50%, then the variance is 0.5² = 0.25. The correlation of returns of the two assets is 0.64.

What is the standard deviation of the portfolio?

	Asset A	Asset B
Portfolio Weights	0.07	0.93
Variances	0.2601	0.4356
Standard Deviation	0.51	0.66

The standard deviation of the portfolio is ____. (Enter your answer in decimal form. Round to four decimal places.)
