stores at $0.50 per unit per annum. The cost to place an order is $100. a) Calculate: i. the economic order quantity (EOQ) (8 marks) ii. the number of orders (2 marks) i. the annual ordering cost (5 marks) ii. the annual carrying cost (5 marks) Question 2 a. Workers are randomly assigned to three (3) machines on an assembly line. The number of defective parts produced by each worker for one (1) day is recorded, and the data shown in the table below. Also included is a partial ANOVA table. At the 5% level of significance can it be concluded that the mean number of defective parts produced by the workers is the same?
