Temperature is used to measure the output of a production process. When the process is in control, the mean of the process is = deviation is = = 0.2. a. Construct the chart for this process if samples of size 6 are to be used (to 2 decimals). 134.4 and the standard UCL = LCL = b. Is the process in control for a sample providing the following data? 128.1 129.5 128.5 128.3 128.6 128.6 x = (to 2 decimals) Conclude that the process - Select your answer - in control. c. Is the process in control for the following data? 129.5 128.1 128.1 128.7 128.8 129.3 x = (to 2 decimals) Conclude that the process - Select your answer - in control.
