company's training program, participants learn how to conduct an analysis of clients' insurability. The goal is to have participants achieve a time in the range of 32 to 45 minutes. Test results for three participants were the following Armand, a mean of 370 minutes and a standard deviation of 20 minutes, Jerry, a mean of 360 minutes and a standard deviation of 4,0 minutes, and Melissa, a mean of 38.5 minutes and a standard deviation of 15 minutes. a.Compute process capability for the participants and determine whether each is capable. (Do not round intermediate calculations. Round your answers to 2 decimal places.) Cok Participants Armand Jerry Melissa A process that makes plastic cell phone cases uses an injection molding machine to create the cases. The target thickness of the cases is set by a controller on the machine, and is currently set to deliver a case with a thickness of 5.0mm. Three cases are pulled each hour, and the thickness of those cases is measured. The machine has been operating smoothly over the last month, and the data from the samples have a sample mean of 510mm, and a sample standard deviation of 04mm. The specs for the thickness of the cell phone case have been set at 47mm -5.5mm a) Is this process capable? b)What target should the machine be set for to ensure capability while still using the least amount of plastic? c) If plastic currently represents an annual cost to the company of $10,000,000, approximately how much money will the company save by making this change? a) No b) 5.25mm c) It will not save any money on plastic, as the target is higher. However, rejects will be reduced due to the process now being copable. o) Yes b) 4.86 mm c) $470.600 a) Yes b) 5.1mm a) Yes b) 5.0 mm c) Savings will be neglible a) Yes b) 4.94mm c) $313,700 a) Yes b) 4.86MM c) $493,800 a) Yes b) 4.94mm c) $313.700 a) Yes b) 4.86MM c) $493,800 a) Yes b) 4.94mm c) $323,900
