Question
E) none of the above 20) McDaniel Shipyards wants to develop control charts to assess the quality of its steel plate. They take ten sheets of 1" steel plate and compute the number of cosmetic flaws on each roli. Each sheet is 20' by 100. Based on the following data, develop limits for the control chart, plot the control chart, and determine whether the process is in control. Number of flaws Sheet 2 4 5 8 0 10 21) The mean and standard deviations for a process are -90 and -9. For the variable control chart, a sample size of 16 will be used. Calculate the standard deviation of the sampling distribution. Standard Deviation: 22) which of the following is not one of the major categories of costs associated with quality? A) prevention costs B) appraisal costs C) internal failures D) external failures E) None of the above; they are all major categories of costs associated with quality. onest self-evaluation of your efforts in this class What arade wonld uon rive vourcolf for tho folanExplanation / Answer
Total Units samples= 10
Total defects = 14
Defect rate , C- Bar = 1.4
Standard deviation = 1.183216
Z value = 3
Upper control limit (UCL)= 4.949648
Center Line- 1.4
Lower Control limit= 0
The Process is out of control because some data is above the UCL
22) Which of the following is not one of the major categories of costs associated with quality
e. none of the above; they are all major categories of costs associated with quality
