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?

An Xbar control chart designed with L=3 and sample size n=4 has control limits UCL=342.05 and LCL=317.95. If the mean shifts to mu1=335 beta is found to be 0.9603. What would be the ARL1 after the mean shifts to mu1? 4.2 10.06 2.03 not enough information 25.22

621 Daily samples of 100 power drills are removed from Drill Master's assembly line and in- spected for defects. Over the past 21 days, the following information has been gathered. Develop a 3 standard deviation (99.73% confidence) p-chart and graph the samples. Is the process in control?

9. A pizza delivery service wants to track their delivery times. They take eight samples of four deliveries and record the following data. What are the upper and lower control limits of their R-chart?  (Note:  Although it looks similar, the data in the table below is different from the data in the table relating to the UCL and LCL for the X-bar chart.)   Sample # 1 2 3 4 5 6 7 8 Item #1 21.1 20.2 24.1 22.6 21.2 20.0 22.0 20.2 Item #2 21.7 20.6 21.0 22.1 24.1 24.2 24.6 24.9 Item #3 23.5 24.9 23.2 23.0 20.6 22.8 23.4 22.8 Item #4 20.0 23.5 24.8 25.0 20.7 23.2 23.3 24.5   Group of answer choices 7.0, 0.5 9.3, 0.0 8.5 0.0 10.1, 0.0
