Little Dogs Studies on Bathroom locks

The Middleborough High School recently remodeled the school bathrooms. Students noticed that the new bathroom locks were likely to break so the doors wouldn’t lock. Within a month, more than half of the locks were already broken. During the school passing period, the broken locks made it harder to use the bathroom quickly and make it to the next class on time. Replacement locks have been ordered, but they are on back-order and won’t be available until the next semester. The student association petitioned the school administration to find a fix for the problem. To determine how large of a problem this was, the student association gathered the data that is shown in Figures 1-3.
