I'm gonna have to go with C on this one. The AIC is all about finding the Goldilocks model - not too complex, not too simple, but just right. And RestPulse seems to be that sweet spot. Though I do wonder if the 'RestPulse' variable is actually a secret agent in disguise.

Okay, let's think this through. The AIC statistic rewards models that fit the data well while also being as simple as possible. Looking at the options, the model with just 'RestPulse' has the lowest AIC, so that must be the champion. I'm picking C.

This is a tough one, but I think the answer is C. The AIC statistic is all about finding the most parsimonious model, and the one with just 'RestPulse' looks like the clear winner here. I'm feeling pretty confident about this one!

Hmm, the question is asking for the champion model based on the AIC statistic. If I'm reading this correctly, the model with 'RestPulse' has the lowest AIC, so that must be the winner. I'm going with C.

Okay, let's see. The AIC statistic is used to evaluate model fit, and the lower the AIC, the better the model. Looking at the results, the model with the lowest AIC is RestPulse, so I'm going with C.

I think the champion model is D) RunTime because it has the lowest AIC statistic.
