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
To determine the mean age, you need to find the average age of the randomly selected employees.
Here's how you can do it step by step:
1. Add up all the ages: 34 + 41 + 28 + 35 + 27 + 44 + 48 + 29 + 33 + 39 = 358.
2. Divide the total sum by the number of employees (which is 10 in this case): 358 / 10 = 35.8.
Therefore, the mean age of the randomly selected employees is 35.8.
So, the correct answer is option c) 35.8.
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.
To determine the mean age, you need to add up all the ages and divide the sum by the number of employees.
The sum of the ages is 34 + 41 + 28 + 35 + 27 + 44 + 48 + 29 + 33 + 39 = 358.
There are 10 employees.
So, the mean age is 358 / 10 = 35.8.
Therefore, the correct answer is c) 35.8.
