The upper and lower control limits for one checkpoint, salt content in Lay's chips, are 2.22% and 1.98%, respectively, and the population standard deviation of the salt content is 0.07%. Angela is now going to evaluate a new salt process delivery system and wants to know if the upper and lower control limits at 3 standard deviations for the new system will meet the upper and lower control specifications noted earlier. The data (in percents) from the initial trial samples are: Sample 1: 1.98, 2.11, 2.15, 2.06 Sample 2: 1.99, 2.0, 2.08, 1.99 Sample 3: 2.20, 2.10, 2.20, 2.05 Sample 4: 2.18, 2.01, 2.23, 1.98 Sample 5: 2.01, 2.08, 2,14, 2,16

Provide the report to Angela.

Please kindly help me and give the detailed explanation of the calculation of the upper and lower control limits of the new salt process, and if it is possible, could you tell me what does it means if the upper control limit of new process is lower than the previous process? Thank you so much
