Measures Of Dispersion

Measures Of Dispersion
In manufacturing company, the number of employees in unit A is 40, the mean is USD $6400 and the number of employees in unit B is 30 with the mean of Rs. 5500 then the combined arithmetic mean is
9500
8000
7014.29

Measures Of Dispersion
Considering the sales, the coefficient of variation for product X is 9.3% and the coefficient of variation for product Y is 8.9% then sales fluctuation of
product X is higher
product Y is higher
product X is lower
product X and Y is lower
