given the bar graph below create a grouped frequency distribution.

the graph is numbered up the side by twos to 22,
along the bottom there are countries that go up to a number.
united states up to 10
argentina up to 22
united kingdom up to just under the ten
phillipines is just barely under the united kingdom
sweden in inbetween 10 and 12
spain is right where phillipines is
thailand is on the 12
south africa is in between the 12 and 14
poland is in between the 14 and 16
russia si the same as spain
mexico is ust above the 10

im not sure why they have some of the lines in between the numbers, and in different areas. im confused, please help.

To create a grouped frequency distribution using the given bar graph, follow these steps:

Step 1: Determine the range
Look at the numbers on the side of the graph and find the highest and lowest values. In this case, the lowest value is 2, and the highest value is 22. So, the range is 22 - 2 = 20.

Step 2: Determine the class width
The class width determines the size of each group or interval in the frequency distribution. To find the class width, divide the range by the desired number of groups. Generally, it is recommended to have around 5-15 groups, so for this example, let's aim for 10 groups.
Class width = range / number of groups
= 20 / 10
= 2

Step 3: Create class intervals
Starting from the lowest value, add the class width repeatedly to define the intervals. In this case, the lowest value is 2, and the class width is 2. So, the class intervals can be defined as:
2-4, 4-6, 6-8, 8-10, 10-12, 12-14, 14-16, 16-18, 18-20, 20-22

Step 4: Count the frequencies
Count how many countries fall into each interval. Based on the information provided, you can determine the frequencies for each interval:
2-4: 0 (no countries)
4-6: 0 (no countries)
6-8: 0 (no countries)
8-10: 2 (United States, Mexico)
10-12: 3 (United Kingdom, Sweden, Russia)
12-14: 2 (Thailand, Spain)
14-16: 1 (Poland)
16-18: 0 (no countries)
18-20: 0 (no countries)
20-22: 1 (Argentina)

Step 5: Create the grouped frequency distribution table
Now, you can summarize the information in a grouped frequency distribution table:
-------------------------------------
Class Interval | Frequency
-------------------------------------
2-4 | 0
4-6 | 0
6-8 | 0
8-10 | 2
10-12 | 3
12-14 | 2
14-16 | 1
16-18 | 0
18-20 | 0
20-22 | 1
-------------------------------------

That's it! You have successfully created a grouped frequency distribution based on the given bar graph.
