A textile manufacturer wants to set up a control chart for irregularities (eg, oil stains, shop soll, loose threads, and tears) per 100 square yards of carpet. The following data were collected from a sample of twenty 100-square-yard pieces of carpet: Sample 2 3 4 S Irregularities 13 9 7 11 4 Sample 7 8 9 10 Irregularities 10 5 10 7 18 Sample Irregularities 11 16 12 13 14 15 a. Using these data, set up a c-chart with 3 The UCL equals and the LCL, equals (Enter your responses rounded to two decimal places) 11 18 16 15 Sample Irregularities 16 15 17 12 18 5 19 20 6 4
