You have six scanner technicians. Three work first shift (D), three work second shift (A), and each is assigned to a specific scanner, which is noted below. Scanning became backlogged in the past week, so you have decided to evaluate the technicians' productivity. You have each scanner record their daily productivity over the next two weeks. Since they do not have other department responsibilities, all their time is spent on scanning. All technicians worked their full 8-hour shift daily for the two-week (10 workday) period under study except Teresa, who had one half day, and John, who had one personal day.
