Temperature is used to measure the output of a production process. When the process is in control, the mean of the process is \( \mu=125.5 \) and the standard deviation is \( \sigma=0.5 \). (a) Compute the upper and lower control limits if samples of size 6 are to be used. (Round your answers to two decimal places.) \[ \begin{array}{l} \mathrm{UCL}= \\ \mathrm{LCL}= \end{array} \] Construct the \( \bar{x} \) chart for this process. (b) Consider a sample providing the following data. Compute the mean for this sample. (Round your \( \bar{x}= \) Is the process in control for this sample? Yes, the process is in control for the sample. No, the process is out of control for the samp (c) Consider a sample providing the following data.
