Question 6. You are to construct an appropriate statistical process control chart for the average time (in seconds) taken in the execution of a set of computerized protocols. Data was collected for 30 samples each of size 40 , and the mean of all sample means was found to be 35 . What is the LCL of a 2.96 control chart? The standard deviation of the sample-means was known to be 4.5 seconds. Your answer should be rounded to ONE place of decimal. Question 7. A process has a process capability ratio, Cp=1.38. At some time the process seems to have a mean shifted left of the center. The process capability index, Cpk, is found to be 0.84, and the mean is left-shifted, that is the current mean is mess than the mean of the control chart. Determine the Z(UTL) with respect to the current left-shifted mean
