A quality analyst wants to construct a sample mean chart for controlling a packaging process. So, the last week, he randomly selected some samples and weighed each. This weight must be in the range of 202. The data from that activity is as below. Weight Day Package1 Package 2 Package 3 Package 4 1 23 22 23 20 2 23 21 19 21 3 20 19 20 21 4 18 19 20 17 5 18 20 22 22 a) Calculate upper and lower two sigma chart control limits. Based on the chart, is this process under control? b) is the process capable well enough? Which capability measure is more accurate for this process? 2. Three production processes - A, B, and C - have the following cost structure: Process A B C Fixed Cost per Year $120,000 90,000 80,000 Variable Cost per Unit $3.00 4 4.5 a) What is the most economical process for a volume of 8,000 units? b) How many units per year must be sold with each process to have annual profits of $50,000 if the selling price is $6.95 per unit? c) What is the break-even volume for each process?
