The c chart representing the number of nonconforming product

The c- chart representing the number of non-conforming product in a defined sample is based on the Normal distribution: a. True b. False The u- chart representing the number of nonconformities in a defined Area of Opportunity is based on the binomial distribution: a. True b. False The purpose of the Nonconformities Retina System is: a. To provide guidance as to the degree of importance assigned to various nonconformities b. To reduce cost c. To provide customer with a basis for evaluating product quality d. To provide the foundation for the use in developing the Demerits control charts In an aircraft assembly-line, the number of missing rivets in an aircraft wing of each aircraft is used to determine the assembly quality. The following SPC chart would be the proper choice to Improve and control the production process: a. The p-chart b. The np -chart c. The c -chart d. The u - chart e. The X-bar chart In exploring the high variation, showing on the process control chart chosen in question 26, you have discovered that the missing rivets can be the result of variation in the diameter size of the special aluminum rivets used, your next move will be to: a. Request engineering change to reduce the hole sizes to accommodate variation the rivet diameter b. Set up a sorting process for the rivets to select the proper diameter size c. Apply suitable variable control charts to the rivet production process d. Instruct the operators responsible for riveting to select the suitable-diameter-rivet, before riveting Action taken in response to question 27, resulted in a marginal Improvement In quality, and raised concern about the diameter of the hole, which is manually drilled prior to the riveting process. What would be the next step to toke to assure the quality of the rivet hole. a. Inspect each hole diameter prior to riveting b. Inspect samples of hole diameters using Go-No-Go gauges, and use a p-chart for process control c. Inspect samples of hole diameters, using expandable Plug-gauge and a micrometer, and use variable control charts, aiming towards process improvement. d. Add a separate process to determine the holdings strength of nonconforming, sample Rivets to assure proper functionality Control charts for attributes are simpler. In comparison to the control charts for variables, being that they require a single chart In comparison to the two charts that are required for variables: a. True b. False Control charts for attributes provide more information about the Quality Characteristics under consideration in comparison to the control charts for variables. a. True b. False
