To find the mean age, you need to sum all the ages and then divide by the number of employees.

Let's calculate that:

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

    The total sum of the ages is \( 358 \).

  2. Number of employees: There are 10 employees.

  3. Calculate the mean: Mean = Total sum of ages / Number of employees Mean = \( 358 / 10 = 35.8 \)

So, the mean age is \( 35.8 \).

The correct response is: 35.8.
