Defects: 7 0 9 13 3 10 3 4 6 6

Part 2 a. Assuming that 10 observations are adequate for these purposes, determine the three -sigma control limits for defects per shirt. The UCLc equals enter your response here and the LCLc equals enter your response here. (Enter your responses rounded to two decimal places. If your answer for LCLc is negative, enter this value as 0.)
