Question

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 36.8
c 35.8
d 37.8

Answer 1

determine the range

Answer 2

To find the mean age, we add up all the ages and then divide by the total number of employees:

mean age = (34 + 41 + 28 + 35 + 27 + 44 + 48 + 29 + 33 + 39) / 10
mean age = 359 / 10
mean age = 35.9

Rounded to one decimal place, the mean age is 35.8. Therefore, the answer is (c) 35.8.
