A study on the processing times for a stamping operation revealed that the processing time for a manufacturing batch follows a Normal distribution with an average of 14 minutes and a variability of 49 square minutes. The process has an infinite queue and receives 3 batches per hour (for example, suppose the time between arrivals follows an exponential distribution). A project is being considered to reduce variability. You oversee this project and need to make investment recommendations. For this you will establish the basis of the system
