Greengage, Inc., a successful nursery, is considering several expansion projects. All of the alternatives promise to produce an acceptable return. Data on four possible projects appear in the following table:

Project	Expected return	Range	Standard deviation
A	12.5%	6.1%	3.5%
B	12.6%	5.8%	3.8%
C	12.2%	5.4%	3.6%
D	12.2%	4.5%	2.7%

a.Which project is least risky, judging on the basis of range?

b.Which project has the lowest standard deviation? Explain why standard deviation may not be an entirely appropriate measure of risk for purposes of this comparison.

c.Calculate the coefficient of variation for each project. Which project do you think Greengage's owners should choose?
