A group of seventh grade students at Edison Junior High School took a random poll over whether there is enough time between classes and how much time they think is needed. 85% percent of the population at Edison think that

in fact there is not enough time between classes. 15% percent were ok with current amount of passing time.  60% of these statistics are from seventh grade and 40% of these statistics were from the eighth grade. The students also told us how much time they felt was needed, an average of five minutes. The problem with that is that the day is lengthened by about 15-20 minutes.  So the logical solution would be to let the seventh grade

students out one minute before the eighth grade. Then the seventh grade will get a head start to their next destination, some of which are in the cluttered eighth grade hallways.
 

To the right, is a pie chart that shows what portion of people voted to what  amount of time. As you can see the largest portion is 5 then 4, 6, 8, 7, then 10.
