A control chart is used for monitoring a process mean ( 7 ) that is normally distributed with a mean of u and a standard deviation of o, and the sample size is n = 5. A 3-sigma limit (u +30z) is used as control limits. Two decision rules are given here. Rule 1: If one or more of the next seven samples yield values of the sample average that fall outside the control limits, conclude that the process is...

Smith and Johnson Industries has decided to use a p-Chart with 3-sigma control limits to monitor the proportion of defective galvanized pipes produced by their production process. The quality control manager randomly samples 150 galvanized pipes at 16 successively selected time periods and counts the number of defective galvanized pipes in the sample. Step 1 of 8: What is the Center Line of the control chart? Round your answer to three decimal places. Step 2 of 8: What value of...

Control charts are to be kept on the thickness measurements for a process that rolls 10-gage copper sheets. The current specification in the sheets is 0.1360+0.0020 inch. After collecting 25 samples of n 5 measurements at approximately half-hour intervals, the data were used to determine Σ L:3.421 inches and R.-0.044 inches, with i1 to 25. Assume that the quality...

The Operations manager at a large widget factory is complaining that since the company has changed to a cheaper supplier for one of the raw materials used for widgets, the quality of their widget has changed. In fact, he has one of the final widgets that has a strength testing below their spec. The new operations employee had previously taken 5 samples each week over a 10-week period, and logged the data in the chart below. Calculate upper and lower...
