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
36.8
35.8
To find the mean age, you add up all of the ages and then divide by the total number of employees.
34 + 41 + 28 + 35 + 27 + 44 + 48 + 29 + 33 + 39 = 348
Mean age = 348 / 10 = 34.8
Therefore, the mean age of the randomly selected employees is 34.8 years.
