deviation of wages is 110. The coefficient of variation is
Select one:
O a. C.V.= 500 percent
O b. C.V.= 15 percent
O c. C.V.= 30 percent
O d. C.V. =20 percent
What is the answer

Answer 1

Answer:

The correct answer is (d) 20 percentage

Step-by-step explanation:

Given data

Average wages of workers of a factory = 550 per month

 ⇒mean of the wages of workers = 550

The standard deviation of wages = 110

Here we need to find the coefficient of variation    

the formula for coefficient of variation is given by

         s = ( standard deviation / mean) 100

           = $\frac{110}{550}$ ×100 = $\frac{1}{5} (100)$ = 20 percentage

⇒ the correct answer is (d) 20 percentage
