The ages, in years, of randomly selected employees are 34, 41, 28, 35, 27, 44, 48, 29, 33, and 39. Determine the mean age.
A. 39.8
B. 37.8
C. 36.8
D. 35.8
To determine the mean age, add up all the ages and then divide by the total number of employees.
34 + 41 + 28 + 35 + 27 + 44 + 48 + 29 + 33 + 39 = 358
358 (sum of all ages) / 10 (number of employees) = 35.8
Therefore, the mean age is 35.8 years.
The answer is D. 35.8
