Q1. Rolls of coiled wire are being monitored. A special sample containing 20 rolls has been examined, and the number of defects per roll are to be recorded in a table. Go to ChatGPT, then enter “Generate a dataset of the number of defects per roll observed in 20 rolls of coiled wire”. Copy the generated data values to Microsoft Excel, with the headings being “Observation” and “Number of Defects”. Then using the data values, answer the following questions. (a) Plot the values on a control chart using three standard deviation control limits. (2] (b) Is the process in control? (1] (c) Using z =+ 2, analyze the data of the “number of defects” using a median run test and an up/down run test to determine if the data is truly random. (2]
