Temperature is used to measure the output of a production process. When the process is in control, the mean of the process is =127 and the standard deviation is =0.8. a. Construct an x chart for this process if samples of size 5 are to be useh)(to decimals). UCL=LCL= b. Is the process in control for a sample providing the following data? \begin{tabular}{lccc|c|c} 128.6 & 128.7 & 129 & 129.1 & 129.1 & 128.7 \\ x= & & (to 2 decimals) & & \end{tabular} Conclude that the process in control. c. Is the process in control for the following data? \begin{tabular}{llll|l|l} 129.5 & 129.3 & 129 & 129.5 & 129.5 & 128.5 \\ x= & (to 2 decimals) & & \end{tabular} Conclude that the process in control
