Answer:
14
Step-by-step explanation:
To find the mean of a data set, add together all the values, then divide by the number of values.
Add all the values
Values: 5, 9, 15, 18, 22
Add: 5+9+15+18+22=69
Divide by the number of values. In this case, there are 5 values.
69/5
13.8
To the nearest whole number:
13.8
The tenth place is an 8, which is greater than 5, so we will round up.
13.8-->14
The mean is 14
