data on four possible projects appear in the table:

EXPECTED RETURN RANGE STANDARD

DEVIATION

A 12.8% 5.6% 3.7%

B 13.4% 4.3% 3.6%

C 11.5% 4.6% 2.7%

D 12.1% 6.3% 3.5%

a.) WHICH PROJECT IS LEAST RISKY, judging on basis of range?

b.) WHICH PROJECT HAS THE LOWEST STANDARD DEVIATION? EXPLAIN WHY SD MAY NOT BE AN ENTIRELY APPROPRIATE MEASURE OF RISK FOR PURPOSES OF THIS COMPARISON.

c.) CALCULATE THE COEFFECIENT OF VARIATION FOR EACH PROJECT. WHICH PROJECT DO YOU THINK GREENGAGES OWNERS SHOULD CHOOSE?
