Answer: a c-chart
Explanation:
An X-bar chart or mean chart is used to monitor the shifts in the process mean and an R-chart is used to monitor the changes in process dispersion. A p-chart is used to control the attributes and measures the percent defectives in a sample. Hence the company cannot use these charts to monitor the variability in the number of defects. A c-chart is used to monitor the number of defects per unit of output. Hence the answer is c-chart.

The dataset below is the observed number of defects from inspecting 25 successive wafers each containing n= 100 chips. Here the wafer is the inspection unit. (a) Create the appropriate control chart to control the data. (b) From the control chart, would you conclude that the process is in statistical control? (c) If any out of control points by Western Electric runs rule 1 are observed, assume they have assignable causes and can be omitted from control limit estimates. Create...

An accounts department is concerned about the number of internal purchase forms that its users completed incorrectly. As a result they are monitoring the proportion of purchase forms that were not completed correctly. This was chosen, rather than measuring the actual number of defects, because any number of defects on a form required about the same effort to revise. The following table shows number of forms completed incorrectly "out of 200 forms" that is processed each day. Construct a control...

Motorola used the normal distribution to determine the probability of defects and the number of defects expected in a production process. Assume a production process produces items with a mean weight of ounces. a. The process standard deviation is .10 ounces, and the process control is set at plus or minus 1.25 standard deviations. Units with weights less than 13.875 or greater than 14.125 ounces will be classified as defects. What is the probability of a defect (to 4 decimals)? In...
