I think statement I is false, skewness isn’t about how peaked it is.

Wait, the mean can be different from the mode? That’s surprising!

I feel like statement III is tricky; I know the mean and median are equal in symmetric distributions, but the mode can vary.

I'm not so sure about statement I; I thought skewness was more about the shape rather than how peaked it is.

Okay, I've got it. Statements 2 and 4 are the true ones - skewness is about asymmetry, and it can be positive, zero, or negative. I'm confident in selecting option B.

Hmm, I'm not entirely sure about statement 1. I know skewness is related to the shape of the distribution, but I can't recall if it specifically measures "peakedness." I'll have to think this through carefully.

This looks straightforward. Statements 2 and 4 clearly describe the properties of skewness, so I'll go with option B.

I'm a bit confused by the difference between skewness and kurtosis. I'll need to review my notes to make sure I understand which one measures "peakedness" versus asymmetry.

Okay, let me think this through. Skewness is about the asymmetry of the data distribution, so statements 2 and 4 seem relevant. I'll need to double-check the definitions of mean, median, and mode to determine if statement 3 is true.

Haha, I bet the mode and median will be the same for a symmetric distribution. That's just common sense! Option C seems like the way to go here.
