You want to determine the upper control line for a p chart for quality control purposes. You take several samples of size 50 items in your production process. From the samples you determine the fraction defective/mean proportion (or p bar used in p-control chart) is 0.006 and the standard deviation is 0.011. If you want to establish a 3-sigma "p" control chart, which of the following is the resulting UCL value for the line?
