1. When transforming data to stabilize the variance A. We can plot the log of the standard deviation at each experimental condition against the log of the Mean of the experimental condition to determine a suitable transform function B. We would verify the transformed data has a stabilized variance C. We will use the transformed response in place of the original response when estimating significance factors of the model D. All of these are correct 2. The process control plan is important because it A. Defines the improved process in a way that such improved performance can be maintained B. Shows those inside and outside the process how all the pieces go together to support consistent production of an acceptable product or service C. Provides a way to maintain the gains D. All of these are correct 3. For the interpretation of control charts select the statement that does NOT apply. A. Process upsets or shifts can trigger Out of Control conditions B. Special Causes of Variation can contribute to an Out-of-Control situation C. Unusual patterns of data points in a process could indicate an Out-of-Control situation D. Defects shown on a Control Chart clearly indicate a process is Out-of-Control
