Answer:
We have to put the data for purchased item in a frequency table.
Step-by-step explanation:
The diagram is attached below.
Firstly we have to see that how many customers fall under range [tex]0 to 5[/tex].
Then [tex]5 to 10[/tex].
Then [tex]10 to 15[/tex].
Finally
[tex]15 to 20[/tex].
If we go through the items purchased by customers we can see that item ranges from [tex]0 to 5[/tex] have [tex]4[/tex] customers.
Item purchased range from [tex]5 to 10[/tex] have [tex]2[/tex] customers.
Item purchased range from [tex]10 to 15[/tex] have [tex]7[/tex] customers.
Item purchased range from [tex]15 to 20[/tex] have [tex]1[/tex] customers.
Total number of customers = [tex]14[/tex]
As we have total [tex]14[/tex] number of customers and they have varied quantity of items purchased.
