Two catalysts are being analyzed to determine how they affect the mean yield of a chemical process. Catalyst 1 is currently used, but catalyst 2 is acceptable.  Since catalyst 2 is cheaper, it should be adopted, providing it does not change the process yield.  An experiment is run in the pilot plant, and 8 batches are made with each catalyst.  Assume that yield is approximately normally distributed and that yield variance is known for each catalyst. Which statistical test should be used to determine whether the mean process yield of catalyst 2 is the same as catalyst 1?

Controllable process variation is the variation due to [var] 

In which section of a Project Charter would you find the following statement: Raw material inventory levels are averaging 31.2 days, with a high of 45 days. These levels have exceeded the target of 25 days more than 95% of the time in the last three months. We could save $250,000 per year if inventories were at the targeted level. [which]
