Respuesta :

This is quite easy, but anyway:

In order, they are

3, 4, 4, 5, 5, 5, 5, 7, 7

7 - 3 = 4

4 would be the range
The range is the highest number subtracted from the lowest number in the set. So, in this example first put the numbers in the set in least two greatest. So 3,4,4,5,5,5,5,7,7 then the highest number is 7 and the lowest number is 3 so 7-3 is 4 . Hoped that helped ! :)
