To determine the mean age, 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.

  1. Sum the ages: \[ 34 + 41 + 28 + 35 + 27 + 44 + 48 + 29 + 33 + 39 = 34 + 41 = 75 \ 75 + 28 = 103 \ 103 + 35 = 138 \ 138 + 27 = 165 \ 165 + 44 = 209 \ 209 + 48 = 257 \ 257 + 29 = 286 \ 286 + 33 = 319 \ 319 + 39 = 358 \]

    So, the total sum of ages is 358.

  2. Count the number of employees: There are 10 employees.

  3. Calculate the mean: \[ \text{Mean} = \frac{\text{Total Sum of Ages}}{\text{Number of Employees}} = \frac{358}{10} = 35.8 \]

The mean age is 35.8.

So the answer is 35.8.
