The coefficient of variation for a random variable is defined asσ/μ. This coefficient is analternative to the standard deviation as a measure of dispersion; the coefficient of variationmeasures that dispersion in proportional terms. IfY=bX, b6= 0, what is the relationshipbetween the coefficients of variation ofYandX.
