Management wants the box-filling line to be set so that the process average weight per packet is 48 grams. To make sure that the process is in control, an inspector at the end of the filling line periodically selects a random box of 7 packets and weighs each packet. When the process is in control, the range in the weight of each sample has averaged 7 grams. Click the icon to view the table of factors for calculating three-sigma limits for the x-chart and R-chart. a. Design an R - and an x-chart for this process. The UCLR equals grams and the LCLR equals grams. (Enter your response rounded to two decimal places.) The UCL xx equals grams and the LCLx equals grams. (Entor your respanses rounded to two decimal placbs) b. The results from the last 5 samples of 7 packets are shown below. Is the process in control? Explain. The process variability is statistical control and the process average is statistical control. Therefore, the entire process is control
