Question:

Now suppose BlueBolt Bottlers makes some process improvements, thereby lowering the standard deviation of the process to 1.5 ounces, rather than 8 ounces. Using the data in problem 10 and the new standard deviation, calculate the process capability ratio. Is the ﬁlling process able to meet the tolerance limits 99.7% of the time? Does the process provide Six Sigma quality levels? Explain.
