J\&B Pharma has developed a new drug called Kirchisen. The correct dosage has been determined to be 100mg. Patients can receive as little as 98mg or as much as 102mg and still get the full effects of the medicine with no issues. Because of liability issues in the pharmaceutical industry, J\&B concludes that their manufacturing must be able to provide Six Sigma quality. The current process mean is 100mg with a standard deviation of 0.25mg. Part A: What are the upper and lower tolerance limits (UCL and LCL) for Kirchisen? Part B: Is J\&B's manufacturing process currently able to meet the dosage specifications for at least 99.7% of the time? Does it meet the Six Sigma quality level
