It's your first day on the job as a new Operations Manager for a biopharmaceutical manufacturer. You are currently overseeing the pilot plant, and need to ensure that results are consistent. A newly purchased machine, called the Mettler Density Meter, produces results with a standard deviation of 4.66 The following table contains the data for a sample size of five, taken daily over the past 8 days: Day Day 1 Day 2 Day 3 Sample Avg. 988 1013 1001 Day 4 Day 5 Day 6 977 987 1012 Calculate the UCL and LCL at a 99.73 % (z=3) confidence level: a. What is the Upper Control Limit? [Select] e. What is the lower control limit? [Select] Day 7 < 1067 b. What is the Lower Control Limit? [Select] c. Based on your evaluation, is the output of the Mettler Density Meter under control? [Select] f. Based on the updated STD, are the lots now in control? [Select] Day 8 After re-reviewing the documentation for the new machine, you realize that you made a mistake: the standard deviation is supposed to be 18.25, not 4.66 Based on Z=3, answer the following: d.
