Hi Super users
I would like to ask some questions for the process capability (Analyze - Quality & Process - Process capability)
I have made an summary report & have 2 questions during the process
1. Why should I set alpha level (Significance level)? What does this value mean here? What does it impact for the result?
Actually I changed the value, but cannot find the result changed

2. I could see colors are in the cpk values. I guess Cpk 1.33 is spec & when the value is less than it, yellow color pops up
& less than 1, red color pops up.
Where can I change this color spec?

Thanks!!
To alter the color scheme, choose File->Preferences. Select Reports on the left. On the right, click the Manage Rules button. Choose Capability Index and click Edit.

Specifies the significance level for confidence limits.
Often you can change colors schemes in the preferences and sometimes there are options in the preferences>platforms, but I don't use this platform, so I'm not familiar.
