To determine the mean age, you add all the ages together and then divide by the number of employees.
Here are the ages:
34, 41, 28, 35, 27, 44, 48, 29, 33, 39
Now, let's calculate the sum:
34 + 41 + 28 + 35 + 27 + 44 + 48 + 29 + 33 + 39 = 384
Next, divide the sum by the number of employees, which is 10:
Mean age = Total sum / Number of employees = 384 / 10 = 38.4
Therefore, the mean age of the employees is 38.4 years, which isn't one of the options provided. Please double-check the list of ages if you suspect an error.
