Please Help!!!!! The following set of numbers represents the number of hours a group of students spent reading over the course of two weeks.

3, 19, 11, 29, 4, 6, 10, 16, 2, 21, 15, 22, 13, 9, 1, 17, 2, 26, 18, 7
On your own sheet of paper, graph the set on a histogram, using six intervals in the display. Make sure to label your graph.

Answer: (Another way)

Number of hours Number of students

0 - 4 5

5 - 9 3

10 - 14 3

15 - 19 5

20 - 25 2

25 - 30 2

The total number of groups of students is 20, and 5 + 3 + 3 + 5 + 2 + 2 = 20

So this is also correct.

Find 6 intervals to use:

We can use 0-4, 5-9, 10-14, 15-19, 20-24 and 25-29

Then count the numbers from the list in each group:

0-4 there are 5 numbers in this group

5-9 there are 3

10-14 there are 3

15-19 there are 5

20-24 there are 2

25-29 there are 2


Now create the histogram, with the vertical axis labeled from 0 to 5 and the horizontal axis labeled with your six groups:
