Mrs. Baker would of paid
$
4.00
for 8 pounds of bananas.
We know that
To determine the intervals you will need to find the lowest and highest numbers
lowest number------> 1
highest number-----> 35
(1 and 35).
A general rule would be 5-7 intervals,
so
I will choose 5.
Here are the intervals with the number of people that were in each:
[1-7] -----------> (9)
[8-14] ---------> (14)
[15-21] --------> (8)
[22-28] ------> (3)
[29-35]-------> (5)
The total of the frequencies was 39 people, and that is how many numbers there are.
You multiply the numbers
4X0.55= 2.2
but since you need that 0.2 to complete the self you round up to 3 <span />
The reflection will be (-5,2)
