F shows how many students are 59 inches tall
*count the xs*
G shows how many students are 59 inches tall
*count the 5/9s*
H shows how many students are 59 inches tall
*find 59 the # on top shows*
I does not show how many students are 59
*since the graph is grouped into 59-60 you can not possibly know how many are 59 and how many are 60 you only can know that 8 students are between 59 and 60 inches tall*
ANSWER IS I
Hope that helps
