BlueBolt Bottlers has a bottle-filling process with a mean value of 58 ounces and a standard deviation of 6.0 ounces. a. Suppose that the upper and lower tolerance limits are 66 and 50 ounces, respectively. The process capability ratio is 0.444. (Enter your response rounded to three decimal places.) In order for the BlueBolt bottling process to meet the tolerance limits 99.7% of the time, the standard deviation would need to be 2.7 ounces. (Enter your response rounded to one decima place.) b. Now suppose BlueBolt Bottlers makes some process improvements, thereby lowering the standard deviation of the process to 3.5 ounces, rather than 6.0 ounces. The process capability ratio is (Enter your response rounded to three decimal places.)
