The ages, in years, of randomly selected employees are 34, 41, 28, 35, 27, 44, 48, 29, 33, and 39. Determine the mean age.
39.8
37.8
35.8
36.8
To determine the mean age, we sum up all the ages and divide by the total number of ages:
$ \frac{34 + 41 + 28 + 35 + 27 + 44 + 48 + 29 + 33 + 39}{10} = \frac{378}{10} = 37.8 $
The mean age is therefore 37.8 years.
