The mean is approximately 13.36 years.
To find the median, we first need to arrange the ages in ascending order:
10, 10, 10, 10, 10, 10, 10, 11, 11, 11, 11, 11, 11, 11, 11, 11, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 13, 14, 14, 14, 14, 14, 14, 14, 14, 15, 15, 15, 15, 16, 16
The median is the middle value of the set, which in this case is the 40th value.
So the median is 13 years.
The mode is the value that appears most frequently in the set, which in this case is 12 years as it appears 17 times.
Find the mean, median, and mode of the set of values.
