Advanced Vaccine Labs wants to identify an appropriate cost driver for its quality control department costs. The controller, Mike Harris, gathered this data on quality control department costs and two possible cost drivers - the number of hours scientists spent inspecting batches of vaccines and the number of vaccine batches inspected.
