ID Control Chart The defect rate for a product has historically been about 1.5%. What are the upper and lower control chart limits for a p-chart, if you wish to use a sample size of 50 and 3-sigma limits?

ID Crossover A firm is about to undertake the manufacture of a product, and it is weighing the process configuration options. There are two intermittent processes under consideration, as well as a repetitive focus. The smaller intermittent process has fixed costs of $4,300 per month and variable costs of $9 per unit. The larger intermittent process has fixed costs of $12,000 per month and variable costs of $2 per unit. A repetitive focus plant has fixed costs of $30,000 per month and variable costs of $0.80 per unit. At what output does the large intermittent process become cheaper than the small one?

ID Utilization A fleet repair facility has the capacity to repair 800 trucks per month. However, due to scheduled maintenance of their equipment, management feels that they can repair no more than 600 trucks per month. Last month, two of the employees were absent several days each, and only 400 trucks were repaired. What are the utilization and efficiency of the repair shop?

ID Control Chart A manager wants to build 3-sigma x-bar control limits for a process. The target value for the mean of the process is 10 units, and the standard deviation of the process is 3. If samples of size 9 are to be taken, what will be the upper and lower control limits, respectively?
