The following set of numbers is going to be graphed on a histogram. 3, 19, 11, 29, 4, 6, 10, 16, 2, 21, 15, 22, 13, 9, 1, 17, 2, 26, 18, 7 if there are going to be six intervals in the display, what is the length of each interval?

observe the minimum and the maximum number to be graphed. And then divide the max. by the intervals , this will give u the size of the intervals . Size comes approx 4.9 , take it 5. Then some common sense applied and 1-5 hope I helped.
