Decision Making Under Uncertainty, GENG 623

Project 6 Due Date: 4/20/2017

Consider a process with a mean value of 20, upper control limit (UCL) of 30 and lower control limit (LCL) of 10. Plot the following points and determine if the process is in statistical control. If
not, divide the process into groups based on 5 equal time intervals and determine which group has out of control condition. Also indicate what type of Out-Of-Control condition is applicable to each
group.

If this process is six standard deviation (6 ), determine the various capability indexes (Cp, Cpk, and Cpm). For Cpm assume a target value of 21.
