I’m a bit confused about the Logistic Distribution; I don’t think we covered it much in class. Is it even applicable for Capability Analysis?

I practiced a similar question where the Normal Distribution was the answer, so I’m leaning towards that one for this question too.

I think the Exponential Distribution might come into play for processes with time between events, but I can't recall if that's relevant here.

I remember we talked about the Normal Distribution being commonly used for Capability Analysis, but I'm not entirely sure if that's always the case.
