The mean would increase in value to about 27.1.
The mean would stay the same value of about 22.5.
The mean would stay the same value of about 23.8.

Answer 1

Explanation:

the mean would increase to about 24.6 is the answer

if u add all the ages together including the extra 33 you get 271. if u divided this by 11 you get 24.636...

Answer 2

The correct answer is B. The mean would increase in value to about 27.1
If another age of 33 is added to the data, the new mean would be (17 + 17 + 18 + 19 + 22 + 23 + 25 + 27 + 32 + 38 + 33) / 11 = 27.1.
