The data for 30 samples of 8 measurements each were collected from a process at Hawkeye Plastics. They’ve asked you to create an x ̅-chart and an s-chart for the process and to interpret the results for them. a) What values will be used for the centerline, upper control limit, and lower control limit of each chart? (You only need to make a table of the values to answer this question and others like it in this assignment.) b) Create...
