If "NO", please identify BY NAME which of the 11 Shewhart Tests for Stability EACH chart fails. Revised Process Prep Data INDIVIDUALS CHART: What did you get for a center line? What did you get for an upper control limit? What did you get for a lower control limit? Revised Process Prep Data MOVING RANGE CHART: What did you get for a center line? What did you get for an upper control limit? What did you get for a lower control limit? Is the revised process stable? If "NO", please identify BY NAME which of the 11 Shewhart Tests for Stability EACH chart fails.AboveWay Sandwich, Inc. Customer Satisfaction Improvement Deliverable: Regression Analysis Student last name: Your last name here PART 1: Using Lunch & Dinner Data What is the correlation coefficient? What is the regression equation? What percentage of variation is explained by the model? HINT: There are 2 related values that can be used to answer this question. Show them BOTH and explain which value you would recommend using and why. Based on an ANOVA of the regression equation, is the regression equation statistically significant at 5% alpha risk? Why do you you say that it is either statistically significant or not? HINT: Use the results of your ANOVA as the basis for your answer. What is the null hypothesis for ANOVA for a regression equation? PART 2: Using Only Lunch Data What is the correlation coefficient for Lunch? What is the regression equation for Lunch? What percentage of variation is explained by the Lunch model? HINT: There are 2 related values that can be used to answer this question. Show them BOTH and explain which value you would recommend using and why. Based on an ANOVA of the regression equation, is the regression equation statistically significant at 5% alpha risk? Why do you you say that it is either statistically significant or not? HINT: Use the results of your ANOVA as the basis for your answer. Given the results of this study, what should your Black Belt do next to improve customer satisfaction at lunch? PART 3: Using Only Dinner Data What is the correlation coefficient for Dinner? What is the regression equation for Dinner? What percentage of variation is explained by the Dinner model? HINT: There are 2 related values that can be used to answer this question. Show them BOTH and explain which value you would recommend using and why. Based on an ANOVA of the regression equation, is the regression equation statistically significant at 5% alpha risk? Why do you you say that it is either statistically significant or not? HINT: Use the results of your ANOVA as the basis for your answer. Given the results of this study, what should your Black Belt do next to improve customer satisfaction at dinner? AboveWay Sandwich, Inc. Customer Satisfaction Improvement Deliverable: Process CapabilityWhat did you get for Cp? What did you get for Cpk? What, specifically, does this particular Cpk tell you about the process that other Cpk's may not? What did you get for Pp? What did you get for Ppk?What did you get for Z-score? What does this Z-score mean? HINT: Use the z score you calculated in a sentence that explains what it tells you about this process. Using the z score calculated above and a z table, estimate the % of sandwiches that will be made within the 1.5 minute goal. PPM (aka DPMO) beyond the 1.5 minute goal
