Hey, at least they're not asking us to interpret a scree plot. That's where the real fun begins! *winks*

The Pareto chart is pretty clear, and option C just makes the most sense to me. Although, I do wonder if the designer of this exam is a fan of the Pareto principle. *chuckles*

I'm a bit confused about the alpha risk in option B. Doesn't that seem a bit too high? I'll go with option C to be on the safe side.

Option B has an alpha risk of 2.06, which does seem high.

I believe statement D is also correct because it mentions the factors to keep in the mathematical model with a 5% alpha risk.
