Please answer all requirements in detail
High pack weight variation is a problem with considerable implications, because underweight packets lead to customer dissatisfaction and excess weight results in loss of profit, in this example, the weight X of biscuits is monitored to control the process of packaging. Three measurements are taken every hour for a total of 25 samples as mentioned in the Excel file. The objective is to study the manufacturing process stability 1) Using Minitab Software, verify that all hypothesis of Shewhart (Normality and independence) are met 2) In MS Excel, estimate the sample mean and the sample variance of XI, X2 and X3 3) In MS Excel and for each sample, estimate & and R 4) In MS Excel estimate X, and R 6) In MS Excel, 6.1) Determine the Shewhart control chart limits (a = 0.27%) for Xbar and R 6.2) Determine the control charts limits for Xbar and R if a = 1% 7) Using Minitab Software 7.1) Plot the Shewhart Xbar and R control chart (a = 0.27%) 7.2) Plot the control charts limits for Xbar and R if a = 1% 7.3) Compare and interpret 8) In MS Excel estimate ox , dy, and OR (pay attention in how estimate the value of R)Step by Step Solution
