Wait, is this a trick question? I'm going to guess C) maybe, just to keep the exam folks on their toes.

This is a classic case of overthinking it. The answer is clearly D) smaller. Fewer readings means less variability within each sample.

So, the new average range will definitely be smaller than the current average range.

I agree, having only 5 readings per sample will reduce the variability, making the average range smaller.

I think the answer is D) smaller. With fewer readings per sample, the range is likely to be smaller.

Hmm, I'm not sure about this one. I'll go with F) same size, just to play it safe.

This is a tricky one. I'm going with E) larger. Reducing the number of readings per sample is likely to increase the variability within each sample, leading to a larger average range.
