The Canine Gourmet Company produces delicious dog treats for canines with discriminating tastes. Management wants the box-filling line to be set so that the process average weight per packet is 42 grams. To make sure that the process is in control, an inspector at the end ofthe filling line periodically selects a random box of 10 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.

At Quick Car Wash, the wash process is advertised to take less than 7 minutes. Consequently, management has set a target average of 390 seconds for the wash process. Suppose the average range for a sample of 10 cars is 11 seconds. Use the accompanying table to establish control limits for sample means and ranges for the car wash process. The UCL Subscript x overbar equals seconds and the LCL Subscript x overbar equals seconds. (Enter your responses rounded to two decimal places.)
Steps to monitor using the control charts: Now monitor the process. An additional ten days of data have been collected, see table labeled “1st 10 Days of Monitoring Reservation Processing Time” in the Data File. Develop Xbar and R charts for the 1st 10 days of monitoring. Plot the data for the 1st 10 days on the Xbar and R charts. Is the process in control? If the control chart indicates an out-of-control process, note which days, the pattern, and whether it is the Xbar or R chart. Now that we have set up the control charts using enough data from a stable process, the 30 days of data, we will monitor the process. While monitoring the process, what will we use as the upper control limit for the X-bar Chart to compare against our new x-bar values? Enter your response to three decimal places. You do not need to include the units (minutes), ONLY the numeric value. USE DATA TO GET UPPER CONTROL LIMIT
Canine Gourmet Super Breath dog treats are sold in boxes labeled with a net weight of 15 ounces (425 grams) per box. Each box contains 10 individual 1.5-ounce packets. To reduce the chances of shorting thecustomer, product design specifications call for the packet-filling process average to be set at 44.0 grams so that the average net weight per box of 10 packets will be 440 grams. Tolerances are set for the box to weigh 440±14 grams. The standard deviation for the packet-filling process is 1.03 grams. The target process capability ratio is 1.67. One day, the packet-filling process average weight drifts down to 43.0 grams. Is the packaging process capable? Is an adjustment needed? Since the process capability index, Cpk, is nothing, the process ▼ is capable is not capable . (Enter your response rounded to three decimal places
