Ch 6 Assignment A soda bottling plant uses automated filling machines to fill 2-liter bottles with soda. The plant can produce 8000 bottles of soda in an 8-hour shift. The plant's quality manager wants to determine how well the process is operating. He takes a sample of 100 bottles from the bottling line and determines that on an average, each bottle contains 2.06 liters of soda, with a standard deviation of 0.06 liters. The specification limits for a bottle of soda are 2.1 liters and 1.9 liters. Q1. What percentage of bottles produced are within specification limits? Show your calculations. Q2. If you were asked to improve this process to a 6-sigma level, which of the following approaches below is the right way to achieve this? Justify your choice. (a) Increase the process specification limits (b) Decrease the process standard deviation (c) Both a and b
