Chapter 12.2, Problem 10P

Use the data to make a cumulative frequency table,

package weight (kg): 1.25 3.78 2.2 12.78 3.15 4.98 3.45 9.1 1.39

To determine

Use the given data to make a cumulative frequency table.

Explanation of Solution

Given:

The data is :

package weight (kg) : 1.25,3.78,2.2,12.78,3.15,4.98,3.45,9.1,1.39

Calculation:

Arrange the data in increasing order:

1.25,1.39,2.2,3.15,3.45,3.78,4.98,9.1,12.78

Draw a frequency table and cumulative frequency of the frequency of call length:

Package weight	Frequency	Cumulative frequency
0-1.99	2	2
2-3.99	4	6
4-5.99	1	7
6-7.99	0	7
8-9.99	1	8
10-11.99	0	8
12-13.99	1	9
