The ages of the students volunteers at an event are 13, 11, 12, 15, 16, 11, 12,

4, 15, and 11. Find the mean of the ages of students.

12

Step-by-step explanation:

To find the mean, you have to add all of the numbers together and divide by the amount of numbers.

13 + 11 + 12 + 15 + 16 + 11 + 12 + 4 + 15 + 11 = 120

120 / 10 = 12

12

Step-by-step explanation:

add all the ages up together to get 120

Then divide the total by the number of ages

since there are 10 students, divide by 10 to get 12

Mean = average
