A quality control inspector has taken four samples with fi veobservations each at the Beautiful Shampoo Company, measuringthe volume of shampoo per bottle. If the average range for the foursamples is 0.4 ounces and the average mean of the observations is19.8 ounces, develop 3-sigma control limits for the bottling operation.

A microbrewery tracks its output in gallons over a five hour period for each of seven days. Their data is in the table below, and they went ahead and calculated the averages and ranges for the individual samples and the overall averages Their data and the factors tables can be found below.

Cartons of Plaster are supposed to weigh exactly 32 ounces. Inspectors want to develop process control charts. They take five samples of six (6) boxes each and weigh them. Sample means (X-bar) are: 33.8, 34.6, 34.7, 34.1, and 34.2 respectively. Also, the corresponding ranges are: 1.1,0.3, 0.4. 0.7, and 0.3, respectively. The lower and upper control limits of the xbar-chart are respectively O a. None is correct O b. 30.11 and 40.15 O c. 34.01 and 34.55 O d. 33.12 and 34.12 O e. 37.01 and 39.23

Can you please explain the steps to create the control chart ?

Hermitage DNA Labs, LLC collected temperature readings in an analysis process. The data can be found in the Problems Data   Compute the mean and range of each sample and calculate control limits for x-bar and R charts using the appropriate From the charts constructed, does the process appear to be in statistical control?

DESIGNING A CONTROL CHART EXAMPLE   Fujiyama Electronics, Inc. has been having difficulties with circuit boards purchased from an outside supplier. Unacceptable variability occurs between two drilled holes that are supposed to be 5 cm apart on the circuit boards. Thirty samples of 4 boards each were taken from shipments from the supplier as shown in the data listed below.
