PMP Practice: Continually survey project deliverable quality

River Volkov is managing a manufacturing project for Brisket Quantum Group to produce custom warehouse automation components. The quality management plan specifies that the production line must maintain a defect rate below 2.5%. During the third production run, the quality team inspected 800 components and identified 28 defective units. Management wants to know whether the production line is meeting the quality standard and by what margin. What is the actual defect rate for this production run?
