Find Homework #5- Mean quality control chart An engineer at Bearkat Automotive wants to calculate the upper controllimit (UCL) and lower control limit (LCL) for a process. Use the following table to calculate the UCL and LCL and determine if the process is in control. Use a Z value of 3.0 and the standard deviation of 10 Observation A 1 w 4 54 B Sample 2 60 50 60 70 80 60 3 70 60 50 60 D 70 80 70 60 70 1. (5 points) Calculate the grand mean. 2.
