Question: Control limits for an xChart have been determined as: UCLx = 76.4 and LCLx = 73.2 (a) Sample averages for the most recent six samples,

Control limits for an xChart have been determined as:

UCLx = 76.4 and LCLx = 73.2

(a) Sample averages for the most recent six samples, in sequential order, are 73.7, 73.9, 74.7, 75.3, 75.8, and 76.3. What should be concluded about the process average? Should some action be taken? Why or why not?

(b) What would you conclude about the process average if the sample averages for the most recent six samples, in sequential order, were 75.5, 74.9, 76.2, 75.2, 75.5, and 75.1?
