Answer :
Answer:
26 years
Step-by-step explanation:
Given:
The mean age of 9 women = 27 years old
The mean age of 7 men = 25 years old
Question asked:
What is the mean age (nearest year) of all the people in the office?
solution:
By using, mean = sum of observations divided by number of entities
The mean age of 9 women = 27 years old
[tex]\frac{sum of ages}{number of women}[/tex] = [tex]27[/tex]
[tex]Sum of ages of women = 27 \times9 = 243\\[/tex] [tex]years[/tex]
The mean age of 7 men = 25 years old
[tex]\frac{sum of ages}{number of men}[/tex] = [tex]25[/tex]
[tex]sum of ages of men = 25 \times7 = 175[/tex]
Total sum of ages of men and women in the office = 243 + 175
= 418 years
Total number of people in the office = 9 women + 7 men = 16
The mean age of all the people in the office = Total sum of ages of men and women in the office divided by Total number of people in the office
= [tex]\frac{418}{16} = 26.125[/tex]
Therefore, the mean age (nearest year) of all the people in the office = 26 years
