To find the mean (average) age of the given employees, you need to sum all the ages and then divide by the number of employees.
The ages provided are: 34, 41, 28, 35, 27, 44, 48, 29, 30, 39.
First, add all the ages together:
\[
34 + 41 + 28 + 35 + 27 + 44 + 48 + 29 + 30 + 39 = 34 + 41 = 75 \\
75 + 28 = 103 \\
103 + 35 = 138 \\
138 + 27 = 165 \\
165 + 44 = 209 \\
209 + 48 = 257 \\
257 + 29 = 286 \\
286 + 30 = 316 \\
316 + 39 = 355
\]
Now that we have the total sum of ages, which is **355**, we divide this by the number of employees, which is **10**:
\[
\text{Mean} = \frac{355}{10} = 35.5
\]
Thus, the mean age of the employees is **35.5 years**.
