Answer:
15.655
Step-by-step explanation:
To find the mean average of a set of numbers, you add up all the numbers and then divide the sum by the total count of numbers.
For the given set of numbers:
22 + 11 + 21 + 18 + 19 + 18 + 18 + 14 + 25 + 14 + 15 + 14 + 15 + 14 + 19 + 17 + 17 + 20 + 13 + 10 + 14 + 14 + 13 + 11 + 11 + 16 + 16 + 16 + 16 = 454
There are 29 numbers in the set.
So, the mean average is:
Mean = Sum of all numbers / Total count of numbers
Mean = 454 / 29
Mean ≈ 15.655
So, the mean average of the given set of numbers is approximately 15.655.
Hope this helps!
