2.A new process has just been established on your assembly line. The process is supposed to add an average of 4 grams of a deep red coloring to each bottle of nail polish 0.1 gram. The standard deviation is 0.1 gram.
In reference to the problem above, what is the Process capability (Cp)?
-6.57
-0.67
-3.33
-0.33
-None of the above
3. In reference to the same problem in the previous question, what is the resulting Process capability Index (Cpk)?
-6.57
-0.67
-3.33
-0.33
-None of the above
4.Using the Process capability (Cp) and Process capability index (Cpk) measures you determined in the previous questions, the process is described as:
-Capable
-Not Capable
5. In reference to the results you have in the previous questions, which of the following statements is TRUE?\
-Mean is nearer to one specification limit or the other
-Mean moves farther from the middle of the specification limits
-Mean is close to the middle of the specification limits
-None of the above
