Question: 1 . A process that has been brought in - control using control charts has a process average of Xbar = 3 5 and Rbar

1. A process that has been brought in-control using control charts has a process average of Xbar =35 and Rbar/d =0.92. If the specification for the process calls for values between 33 and 41, calculate the capability index Cp for this process in its present condition.
2. A process that has been brought in-control using control charts has a process average of Xbar =35 and Rbar/d =0.92. If the specification for the process calls for values between 33 and 41, calculate the capability index Cpk for this process in its present condition.
3. The Cpk is a superior index for measuring the capability of a process because it includes process _________.
4. True/False: Cpk is always equal to or less than Cp.
5. True/False: Cpk can be a negative value.
6. Cp = Cpk when ______________.
7. Draw two pictures based on the following, it can be hand drawn or a digital picture (attach the file to this question - WORD, PowerPoint or PDF):
A process has been brought in-control using control charts. If the specification for the process calls for values between 33 and 41, Draw the graphs/pictures below. The LSL is 33 and the USL is 41.
Picture #1: Draw the capability plot with respect to the LSL and USL assuming you are only given the value of Cp that you got in question #1. Include appropriate labels for what you show in your drawing. (E.g. LSL, USL and Cp value)
Picture #2: Draw the capability plot with respect to the LSL and USL assuming you are only given the value of Xbar in question #2 and the Cpk that you got in question #2. Include appropriate labels for what you show in your drawing.
