Tellers at First National Bank create electronic data records for each transaction they process. The electronic data records are created in real time (i.e., as the tellers interact with customers) when the tellers enter key information in the required fields of an electronic tracking form. At the end of each day, the bank's manager takes a random sample of 250 electronic data records and assesses the accuracy of each record. An electronic data record is considered "defective" if it contains one or more errors. Construct a control/six-sigma chart to monitor the accuracy of the electronic data record creation process. Suppose the next four days yielded the following sample results: Does it appear that the process of electronic data record creation is "in-control?" What is the UCL? (round to 4 decimal places) Construct the p-chart and plot the sample data. Does the sample data indicate that there is an assignable cause impacting the process? Select one: a. Yes b. No
