The number of items in the backlog can be determined by looking at the "Commitment" column for each
sprint in the provided chart. For Sprint 5, there is a commitment of completing 23 items, which is the highest
among all sprints. This indicates that there are at least 23 items in the backlog to be worked on. This is
consistent with the concept of agile project management, which allows for changes and additions to the project
scope based on customer feedback and changing requirements. References = CompTIA Project+ PK0-005
