Some parts manufactured in an injection molding process are subjected to a certain compressive strength test. 22 samples are taken as shown in the following table which shows the compressive strengths (in psi). Assume that you want to analyze using an xbar-s charts. a-) (4 points) What is the LCL for the X control chart? (use 2 decimals) b-) (4 points) What is the UCL for the X control chart? (use 2 decimals) c-) (4 points) What is the LCL for the s control chart? (use 2 decimals) d-) (4 points) What is the UCL for the s control chart? (use 2 decimals)
