Answer:
therws this random chart from the internet, I think that's what they want, but not sure
The list below shows the quantity of items purchased by customers at a particular checkout counter of a supermarket. 13, 6, 5, 9
, 12, 14, 18, 4, 13, 12, 4, 3, 11, 14 Create a histogram that correctly displays the data.

Answer:
A histogram is a bar-diagram which shows the frequency of certain data.
If we elaborate frequency table, it would be like
Number Frequency
3 1
4 2
5 1
6 1
9 1
11 1
12 2
13 2
14 2
18 1
Where the total number is N = 14
Now, to graph this table as a histogram, we first need to label each axis. The horizontal axis will represent Numbers and the vertical axis will represent Frequency.
Then, the vertical axis will have marked number 1 and number 2. The horizontal axis will have mared numbers from 3 to 18, as the image attached shows.
After that, we will draw a bar, where each height will be the frequence. Refer to the image attached to see the histogram.
Answer:
The histogram can have four ranges.
Step-by-step explanation:
To make a histogram you need to separate the data in ranges and check how many values fall into each range. The number of values that fell in a range is going to be the height of the bar.
Arranging the values in increasing order:
3,4,4,5,6,9,11,12,12,13,13,14,14,18
The minimum value is 3 and the maximum is 18. If you make four ranges (you can choose the number of ranges): from 3 to below 7, from 7 to below 11, from 11 to below 15, from 15 to below 19.
The number of values that fall in each category is:
5 in the range from 3 to below 7 (3,4,4,5,6).
1 in the range from 7 to below 11 (9).
7 in the range from 11 to below 15 (11,12,12,13,13,14,14)
1 in the range from 15 to below 18 (18).
Use the values as heights to draw the histogram.
