Attribute Control Charts can be used in the statistical proc

Attribute Control Charts can be used in the statistical process control for both of Variable and Attribute characteristics, however, Variable Control Charts can only be used for variable characteristics: a. True b. False Consideration for the choice of subgroup (sample) size for p- chart includes: a. The definition of a nonconforming product, or service. b. The definition of a nonconforming product, or service. c. The proportion of nonconforming product, or service (p) d. The product versus service nature of the attribute During process startup, a point falling below the Lower Control Limit should be treated in the following manner: a. Adopt the assignable cause, and incorporate the point in estimating the revised values tor the chart b. Discard the point as out-of-control, and exclude it in estimating the revised values far the chart c. Include the value related to the point, on contingency basis in estimating the revised values for the chart d. Recommend the use of control charts for variables, to explore the process Continuous Process Improvement, is supported by the following manifestation on the p- chart: a. Fewer points falling outside the control limits b. A reduction In the value of the chart center line c. Fewer points falling below the lower control limit d. A larger spread between the upper and lower control limits The P-chart information can also be presented by the following form: a. A Pareto chart, showing the proportions of nonconforming product b. A sp- chart showing process variability c. A q-chart showing the proportion of conforming product d. A Multi-Vari chart showing the cause of the nonconforming proportions. The following is used in the treatment of variable subgroup (sample) size on the p- chart: a. Recalculate the control limit values for each sample sizes a. Determine the average sample size, and calculate the control limits values accordingly c. Establish separate control limit lines for the various sample sizes d. Maintain a uniform sample size, by excluding larger quantities, to maintain uniform control lines e. (a), (b), or (c) During process improvement, in the case of a stubbornly high proportion of nonconforming product, it is conceivable that the use of X-bar and R charts be recommended to pursue, process improvement: a. True b. False The np-chart is easier for machine operators to use for process control, however it is recommended mostly in the following situations: a. Where sample size (n) is large b. Where the value of (p) is small c. Where sample size (n) is uniform d. Where product attribute is easily measured or recognized
