Problem 6-05

Given:

	E(R1) = 0.12
	E(R2) = 0.16
	E(1) = 0.01
	E(2) = 0.02

Calculate the expected returns and expected standard deviations of a two-stock portfolio in which Stock 1 has a weight of 70 percent under the conditions given below. Do not round intermediate calculations. Round your answers for the expected returns of a two-stock portfolio to three decimal places and answers for expected standard deviations of a two-stock portfolio to four decimal places.
