Assignment

1. Interpret the data available in the C08 Case Data workbook, establish a state of statistical control, and evaluate the capability of the process to meet speci fications. Consider the following questions:

what do the initial control charts tell you? Do any out-of control conditions exist? If the process is not in con trol, what might be the likely causes, based on the information that is available? What is the process capability? What do the process capability indexes tell the company? Is MMC facing a serious problem that it needs to address? How might the company eliminate the problems of slow loan processing!

2.The process manager who initiated the trial project implemented the recommendations that resulted from the initial study, Because of her success in using control charts, MMC made a decision to continue using them on that process. After establishing.com trol, one additional sample was taken over the next 20 shifts, shown in second part of the table in the MMC Case worksheet. Evaluate whether the pro cess remains in control, and suggest any actions that should be taken. Consider the following issues: Does any evidence suggest that the process has changed relative to the established control limits? If any out of control patterns are suspected, what might be the cause? What should the company investigate?

(kindly answer the question 1 and it in details with equation need and full reliable answers providing all the needing information for each question line by line)
