To find the percentage of units meeting specifications, we need to determine the proportion of the process distribution that falls within the tolerance range. Using the empirical rule (assuming normal distribution), approximately 99.73% of units fall within 3 standard deviations of the mean. So, for a 6 process (which covers 3 standard deviations on both sides of the mean), almost all units should fall within the tolerance range. Thus, the percentage of units meeting specifications is very high, almost 100%. Regarding whether this meets the technical definition of Six Sigma: The technical definition of Six Sigma requires that the process variation be within 6 standard deviations of the mean, resulting in a defect rate of 3.4 defects per million opportunities. Since this process has a Cp of approximately 1.67, it does not meet the technical definition of Six Sigma, which typically requires a Cp of at least 2.0
