a. Suppose that the upper and lower tolerance limits are 68 and 46 ounces, tespectively. The process capability ratio is (Enter your response rounded to three decimal places.) In order for the BlueBolt botlling process to meet the tolerance limits 99.7% of the time, the standard deviation would need to be rounded to one decimal place.) b. Now suppose BlueBolt Bottlers makes some process improvements, thereby lowering the standard deviation of the process to 2.0 ounces, rather than 4.5 ounces: The process capablify ratio is (Enter your response rounded to three decimal places.) The improved BlueBolt process able to meet the tolerance limits 99.7% of the time. This enough for BlueBolt Bottiers to achieve Six Sigma quality levels
