Consider the following data:

What is the variability in the wages of the workers in Factory - A?

Options

A. `100%` more than the variability in the wages of the workers in Factory - B
B. `50%` more than the variability in the wages of the workers in Factory - B
C. `50%` less than the variability in the wages of the workders in Factory - B
D. `150%` more than the variability in the wages of the workers in Factory - B

Answer

B

Explanation

`"Coefficient of variation"=(S.D)/("Mean")xx100`
`"For factory A"=(40.50)/(540)xx100=7.5`
`"For factory B"=(31)/(620)xx100=5`
`therefore "Variability in wages of A is "50% " more than the variability in wages of B."`
