Answer to Question 1

In general, the mean salary of all employees of the company cannot be obtained by finding the mean of 29,525 and 33,470 because each of these means will have been obtained by averaging a different number of salaries. The mean of 29,525 and 33,470 will yield the mean salary of all employees of the company only if the number of female employees is equal to the number of male employees.

Answer to Question 2

B
