To determine if their 1.001.00 centimeter washers are properly adjusted, Reeves Inc. has decided to use an x‾x‾-Chart which uses the range to estimate the variability in the sample. Average Value = 1.010 Step 1 of 7: What is the Center Line of the control chart? Round your answer to three decimal places. Step 2 of 7: What is the Upper Control Limit? Round your answer to three decimal places. Step 3 of 7: What is the Lower Control Limit? Round your answer to three decimal places. Step 4 of 7: Use the following sample data, taken from the next time period, to determine if the process is "In Control" or "Out of Control". Observations: 1.09,1.09,1.05,1.06,1.021.09,1.09,1.05,1.06,1.02 Sample Mean: 1.0621.062 Step 5 of 7: Use the following sample data, taken from the next time period, to determine if the process is "In Control" or "Out of Control". Observations: 1.03,1.08,1.06,1.01,1.091.03,1.08,1.06,1.01,1.09 Sample Mean: 1.0541.054 Step 6 of 7: Use the following sample data, taken from the next time period, to determine if the process is "In Control" or "Out of Control".
