BlueBolt Bottlers has a bottle-filling process with a mean value of 68 ounces and a standarc deviation of 4.5 ounces. a. Suppose that the upper and lower tolerance limits are 79 and 57 ounces, respectively. The process capability ratio is (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 ounces. (Enter your response rounded to one decimal place.) b. Now suppose BlueBolt Bottlers makes some process improvements, thereby lowering the standard deviation of the process to 2.5 ounces, rather than 4.5 ounces. The process capability ratio is (Enter your response rounded to three decimal places.)
