As part of an effort to reduce process lead time, a Six Sigma project team is testing two different production systems. System A: 10 units had a mean processing time of 60 hours with a standard deviation of 10 hours System B: 15 units had a mean processing time of 50 hours with a standard deviation of 15 hours Using a significance level of α = 0.01, the team’s industrial engineer calculated a 99% confidence interval on the difference in mean processing time of 1.42 ≤ μSystem A – μSystem B ≤ 18.59 . What conclusion should the team make?
