Map du to monitor the analysis of iron levels in human blood. The lines on the control chart were obtained from a control sample with a population mean, of 51.50 mg/dL and a population standard deviation, a, of 3.50 mg/dL (values in mg/dL) Action line 53.42- 52,78 Warning line To monitor the analysis of the iron levels, the laboratory measured 30 replicate control samples every day. Shown below are lists of the mean values of the 30 replicate control samples measured every day over a series of 14 consecutive days (runs). 51.50 50.22 Warning Tine Action line Sort the lists of mean values based on whether they indicate the process should be shut down for troubleshooting or not. All values in the lists have units of mg/dL Run number Shut down for troubleshooting Do not shut down for troubleshooting 51.10, 50.25, 52.75, 53.12, 51.27, 51.58, 52.16 52.70, 51.46, 52.08, 52.00, 51.48, 51.86, 51.81 51.95, 51.66, 51.78, 51.99, 51.51, 50.15, 51.62 51.69, 51.83, 51.05, 51.67, 51.90, 51.84, 51.86 51.43, 51.32, 52.86, 51.37, 53.31, 51.61,50.97, 51.53, 50.41, 51.22, 50.25, 51.08, 50.69, 52.15 50.48, 51.83, 51.67, 52.02, 50.68, 51.00, 50.32 51.82,51.17, 51.04, 51.58, 50.92, 52.35, 52.56, 50.43, 51.34, 50.23, 51.11, 50.67, 50.55, 50.38 50.43 51 17.51 04 5158, 50 92 52 35, 52.568, 50.48, 31.83,51.67, 52,02, 50,68, 50.87 1 09Explanation / Answer
Since all the mean values are between the range of 49.58 to 53.42. Therefore, none of the values require shutting down for trouble shooting.
All the values should be in the column of "Do not shut down for troubleshooting".
Values those are beyond action lines above and below qualify for troubleshooting, which is none in this case.
