You have just used the capability index (Cpk) formulas to compute the two values “min [2, 2.5].” Which of the following is the proper interpretation of these numbers? (Class Example)

You want to determine the lower control line for a p-chart for quality control purposes. You take several samples of a size of 50 items in your production process. From the samples, you determine the fraction defective is 0.006 and the standard deviation is 0.001. If the desired confidence level is 99.7 percent, which of the following is the resulting LCL value for the line? (Textbook Question)
