The production manager at Sunny Soda, Inc., is interested in tracking the quality of the company's 12-ounce bottle filling line. The bottles must be filled within the tolerances set for this product because the dietary information on the label shows 12 ounces as the serving size. The design standard for the product calls for a fill level of 12 plus or minus 0.10 ounces. The manager collected sample data (in fluid ounces per bottle) on the production process and then calculated values for the process capability index and yje process capability ratio.
If the process capability index is 1.473 and the process capability ratio is 1.532 , is the process capable of meeting the design standard at four-sigma quality?
A. no, because the process is not centered correctly
B. yes
C. no, because there is too much data outside the allowable tolerances
If the process capability index is 0.885 and the process capability ratio is 1.253 , is the process capable of meeting the design standard at three-sigma quality?
A. yes
B. no, because there is too much data outside the allowable tolerances
C. no, because the process is not centered correctly
If the process capability index is 1.276 and the process capability ratio is 1.132 , is the process capable of meeting the design standard at four-sigma quality?
A. no, because the process is not centered correctly
B. yes
C. no, because there is too much data outside the allowable tolerances
If the process capability index is 1.071 and the process capability ratio is 1.253 , is the process capable of meeting the design standard at three-sigma quality?
A. yes
B. no, because there is too much data outside the allowable tolerances
C. no, because the process is not centered correctly
