darn it pay attention unit of measure the answer must correspond with the bottom axis not the numbers on top of the histograms we are looking for units of time

I still dont get it. I count the total number of minutes of all students at 225 ( 5×1 + 2×2+ 3×3 + 2X4 … = 225)

The middle number is 112.5 or (225/2) minutes, which falls under the 7 minute interval.
