During the last 4 years, in sequence, an investment has earned annual returns of 5%, 0%, -5%, and 0%. Calculate the geometric average annual return and the estimated (i.e., "sample") standard deviation.

During the last 4 years, in sequence, an investment has earned annual returns of 6%, 0%, -6%, and 0%. Calculate the geometricaverage annual return and the estimatedstandard deviation.

	a.	Geometric average return = -0.063%, Estimated standard deviation = 4.082%
	b.	Geometric average return = 0.000%, Estimated standard deviation = 4.082%
	c.	Geometric average return = 0.000%, Estimated standard deviation = 3.809%
	d.	Geometric average return = 0.000%, Estimated standard deviation = 3.536%
	e.	None of the other answers are correct
	f.	Geometric average return = -0.063% Estimated standard deviation = 3.809%
	g.	Geometric average return = -0.063%, Estimated standard deviation = 3.536%
