This graph compares shoe sizes for a group of 80 two year olds boys and a group of 60 three year olds boys. About how many more two year olds boys have a shoe size of 6 or less, compared to the three year olds boys.
6
15
25
40

25

Step-by-step explanation:

each box represents 25% of the data presented

80 two year old boys were chosen for the study , half of 80 is 40

For the 3 year old boys,  the closest point to 6 is 6.5, and it is located after the line on the left.  This means that only 25% of the boys have shoe sizes of 6.5 or under.  25% of the 60 three-year olds they collected data on is 15.

The difference is 40-15= 25.

There are about 25 more two-year olds wearing a size 6 or under.

hope this helps
