Mean of males: $58,000

Mean of females: $50,000

We cannot conclude that the mean salary of all employees is $54,000

because we need to know the number of male employees and number

of female employees. If the numbers are skewed toward one sex or

the other it will change the mean of all employees.

If there are mostly male employees the mean will be higher than

$54,000. If there are mostly female employees the mean will be

lower than $54,0000. If they are roughly equal in number then the

overall mean will be near $54,000
