    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

    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
