To find the mean age of the employees, you simply sum up all the ages and divide by the number of employees.
The ages provided are: 34, 41, 28, 35, 27, 44, 48, 29, 33, 39.
First, let's sum these ages:
\[ 34 + 41 + 28 + 35 + 27 + 44 + 48 + 29 + 33 + 39 \]
Calculating this step by step:
- \(34 + 41 = 75\)
- \(75 + 28 = 103\)
- \(103 + 35 = 138\)
- \(138 + 27 = 165\)
- \(165 + 44 = 209\)
- \(209 + 48 = 257\)
- \(257 + 29 = 286\)
- \(286 + 33 = 319\)
- \(319 + 39 = 358\)
Now, we have a total sum of ages = 358.
Next, count the number of employees. There are 10 ages listed.
Now, calculate the mean:
\[ \text{Mean} = \frac{\text{Total Sum of Ages}}{\text{Number of Employees}} = \frac{358}{10} = 35.8 \]
Therefore, the mean age is D) 35.8.
