Question 248592
The mean salary of the female employees of one company is $29,525. 
The mean salary of the male employees of the same company is $33, 470. 
Can the mean salary of all employees of the company be obtained by finding the mean of $29,525 and $33, 470?
Not always.
---------------------- 
Under what conditions would the mean of $29,525 and $33,470 yield the mean salary of all employees of the company?
If all females actually had a salary of 29,525 and all males actually
had a salary of 33,470.
