Two factories A and B are located in some Industrial estate. Average wage and its standard deviation are given below separately for A and B. Find out coefficient of variation.

Find out standard deviation and coefficient of variation .

In two factories A and B engaged in the same industrial area, the average weekly wages (in rupees) and the standard deviations are as follows: (i) Which factory, A or B, pays out a larger amount as weekly wages? (ii) Which factory, A or B, has greater variability in individual wages?

X ~ B(400, 1//5) then find its standard deviation
