A process that produces computer chips has a mean of .045 defective chip and a standard deviation of .0035 chip. The allowable variation is from .03 to .05 defect. Compute the capability ratio and comment on it's value.
Process Capability Ratio:
Process capability ratio is a common measure of process capability, which is the long-term performance level of a process under statistical control. This measure is appropriate when the process mean is equal to the average of the specification limits.
Answer and Explanation:
The process capability ratio = (Upper specification limit - Lower specification limit) / (6 * standard deviation) = (0.05 - 0.03) / (6 * 0.0035) =...
