I need help understanding how to solve this problem any other problem like this.

Answer 1

Lower Upper Frequency

1 6 2

7 12 4

13 18 7

19 24 1

25 30 4

Explanation:

We sort the given data to get: 1,4,8,8,9,10,13,14,15,15,15,16,18,24,25,25,27,29

The range is 29-1=28

Class width=28/5=5.6

We round up to get 6

The lowest value is 1. Our lower class limits are:

1

7

13

19

25

The upper class limits are:

6

12

18

24

30

Now our frequency table is:

Amount | Frequency

1-6 2

7-12 4

13-18 7

19-24 1

25-30 4
