A certain language school has two classes for children. Is the range of ages, in years, of the children in the first class equal to the range of ages, in years, of the children in the second class?

1) In each class, the number of children is 18 and the age of the youngest child is 8 years.
2) In each class, the average (arithmetic mean) age of the children is 10 years.
