Make sure to include the control limit calculations below. Is the process out of control? Why? Explain. e- Is there any differences between performances of three shifts? Hint: (Carve out the morning, afternoon, and night shift data into three columns and graph their averages. Explain your findings based on graph. f- Use One Way Analysis of Variance (ANOVA) to compare the three groups (shifts) to test if there is significant differences in the performance of three shift averages. Use Alpha -0.01. Indicate the Null and Alt. hypotheses and explain your findings based on ANOVA table. g- Assume Tolerance limits of 25+1.25 lbs is specified in the sales contract and find the Process Capability index C- Discuss if this process is capable to meet contractual agreement. h- Redo part g for all three shifts separately and determine their Ca- Note that you must carve out the three shifts and find the mean and standard deviations for each shift separately and go through part b calculations for each shift. - If the process average is adjusted to 25.0 lbs. and process standard deviation (answer in part b) is reduced by 80%, what is the new C Are you comfortable for making such recommendation to management? Explain. j- Find the control limits for an X-bar and R chart if a new improved process has average of 25.0 lbs. and R-bar of 1.0 lbs. Assume n-5 for new process control. No graph needed. k- Estimate the amount of credit (S) must be given to DCI (for the past 24 months) if it purchased 14,000 bags per month at cost of $10 per lb. - Provide complete conclusion regarding your findings and make recommendations regarding the filling process in your conclusion paragraph.
