Answer: The mean is 22.
Step-by-step explanation:
If you reorder the terms, (11, 14, 21, 26, 29, 33, 61) you can see that 61 is an outlier. Exclude the value.
Now, add the leftover values together (11, 14, 21, 26, 29, 33) which equals 134.
Finally divide 134/6 (Amount of values) and this equals 22.3(repeating).
Round down to 22.
Hope this helps!
