Temperature is used to measure the output of a production process. When the process is in control the mean of the process is » - 126.5 and the standard deviation is a = 0.5 (a) Compute, the upper and lower controllimis samples of size 6 are to be used.

(b) Consider a sample providing the following data. 126.8 126.2 127.1 126.7 126.4 127.2 Compute the mean for this sample. (Round your answer to two decimal places.) X= Is the process in control for this sample? Yes, the process is in control for the sample. O No, the process is out of control for the sample. (c) Consider a sample providing the following data. 127.3 126.7 126.6 127.2 127.5 129.0 Compute the mean for this sample. (Round your answer to two decimal places.) 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 sample.
