A maintenance group aims to improve the effectiveness of its repair work. The group therefore monitors the number of maintenance requests that require a second visit to complete the repair. On any given week the maintenance group responds to 200 maintenance requests. The following table summarizes the number of those maintenance requests that required a second visit in the last five weeks.
Week Number 1 2 3 4 5
Number of those maintanance requests
that required a second visit
6 8 9 7 3
