Temperature is used to measure the output of a production process. When the process is in control, the mean of the process is u= 131.9 and the standard deviation is o= 0.8 . a. Construct the chart for this process if samples of size 7 are to be used (to 2 decimals). b. Is the process in control for a sample providing the following data? 128.8 129.4 128.7 128.8 129.0 128.9 (to 2 decimals) Conclude that the process - Select your answer - in control. c. Is the process in control for the following data? 128.6 128.5 129.2 129.4 128.9 128.2 (to 2 decimals) Conclude that the process - Select your answer - in control. See full question below

Exercise 19.05 Algo (Statistical Process Control) Question 2 of 7 Hint(s) Check My Work Temperature is used to measure the output of a production process. When the process is in control, the mean of the process is / = 131.9 and the standard deviation is o = 0.8. a. Construct the @ chart for this process if samples of size 7 are to be used (to 2 decimals). UCL = LCL = b. Is the process in control for a sample providing the following data? 128.8 129.4 128.7 128.8 129.0 128.9 = (to 2 decimals) Conclude that the process - Select your answer - V in control. c. Is the process in control for the following data? 128.6 128.5 129.2 129.4 128.9 128.2 x = (to 2 decimals) Conclude that the process - Select your answer - V in control
