Question: The Thermiston production plant's equipment operates two shafts for eight hours and produces 100,000 pieces per day. The design time for producing a thousand pieces was 6.88. The last quarter of an hour is allocated for daily maintenance and the first quarter of an hour for operation. The time for unexpected malfunctions in the shaft was 20 minutes. If there were 1,000 defective units per shelf, what is the overall effectiveness of the laboratory equipment for that day?
