I’m leaning towards A and C too, but I remember something about replacement being tricky in model assessment.

I practiced a question like this, and I feel like both A and C are the right choices, but I’m a bit confused about the replacement part.

I think stratified random sampling without replacement is definitely one of the acceptable methods, but I can't recall if the other one is simple random sampling with or without replacement.

I remember that simple random sampling without replacement is often used, but I'm not sure about the second option.

I'm a bit confused on the difference between simple random sampling with and without replacement. I think without replacement is the way to go, but I'm not 100% sure about the other option. I'll have to review my notes before answering this one.

Okay, let me think this through. Simple random sampling without replacement makes sense since we want to avoid duplicates in the training and test sets. And stratified random sampling is also a good choice to ensure the distributions are representative. I'll go with those two.

Hmm, I'm a bit unsure about this one. I know simple random sampling is acceptable, but I can't remember if with or without replacement is the right approach. And I'm not confident about the other option.

I'm pretty sure simple random sampling without replacement and stratified random sampling without replacement are the two correct options here. Those are the standard methods we've learned for partitioning data.

The key here is to focus on the question and what it's asking for. Since it's asking about influential observations, I think the Cook's D by Observation plot is the way to go.

Hmm, I'm a bit unsure about this one. I know IPSec provides secure network communication, but I'm not sure which of these options would work best with it for accessing files on a NAS. I'll have to think this through carefully.

I'm a little confused by the wording of this question. It doesn't seem to match up perfectly with the answer choices provided. I'll have to re-read it a few times to make sure I understand what they're asking for.

Has to be B, right? I recall it's about categorizing inventory based on quantity needed.

If I had a nickel for every time I saw 'sequential random sampling' on an exam, I'd have... well, a nickel. But hey, at least it's better than 'random sequential sampling', am I right?

I'm more of a 'go big or go home' kind of guy, so I'm picking B and D. Simple random sampling with replacement and sequential random sampling with replacement? That's living on the edge, baby!

I'm going with A and C. Stratified random sampling is a great way to ensure we get a representative sample, and simple random sampling without replacement is a classic.

Woah, hold up! Simple random sampling with replacement? Isn't that just putting the data back in the hat and pulling it out again? Seems a bit like cheating to me.
