A product has specification limits of 6.0 ounces and 6.5 ounces. The company of this product states that the product weighs 6.2 ounces.
If the company wants to have a Cpk of 2.0 or greater, what is the maximum value of the standard deviation (?) so that the Cpk of the process indicates that the company can provide the six sigma process (process capability = 2.0)?
Suppose that the company is operating at a standard deviation (?) of 0.025. What is the range on the mean of the process to maintain a pk of 2.0 or greater?
