To determine the mean age of the employees, you need to sum all the ages and then divide by the number of employees.
The ages are: 34, 41, 28, 35, 27, 44, 48, 29, 33, and 39.
First, we find the sum of the ages:
34 + 41 + 28 + 35 + 27 + 44 + 48 + 29 + 33 + 39 = 34 + 41 = 75
75 + 28 = 103
103 + 35 = 138
138 + 27 = 165
165 + 44 = 209
209 + 48 = 257
257 + 29 = 286
286 + 33 = 319
319 + 39 = 358
Now, we divide the total sum by the number of employees (which is 10):
Mean age = Total sum of ages / Number of employees = 358 / 10 = 35.8
So, the mean age is 35.8.
