Standard deviation versus coefficient of variation as measures of risk Greengage, Inc., a successful nursery, is considering several expansion projects. All the alternatives promise to produce an acceptable return. Data on four possible projects appear in the following table: a$.$ Which project is least risky, based on the range of possible outcomes? 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. $.$ Calculate the coefficient of variation for each project.
