Wait, is this exam going to be on 'skewness' or 'skewering' the competition? Either way, I'm ready to bring home the gold!

Alright, time to shine! Coefficient of skewness, eh? I bet the answer is hidden in those formulas they gave us. *squints eyes* Aha, C looks right to me. Although, I did hear the professor say something about 'skewness' and 'skewed' being similar. Maybe I should double-check that...

I remember the professor mentioning 'skewness' and 'skewed' too. Let's double-check before we finalize our answer.

I calculated it and got -0.415. I think I made a mistake somewhere.

Coefficient of skewness, huh? I remember learning about this in my stats class. Time to put that knowledge to the test. *scratches head* Okay, let's see... I think I'm going with option C.

Ooh, this is a tricky one. But I've got this! Plugging in the values, I'm getting 0.415. Better double-check my work, though. Don't want to be the one who gets it wrong and looks like a fool in front of the class.

Ah, the coefficient of skewness, a measure of the asymmetry in the distribution. Let's see, the formula involves the third central moment divided by the cube of the standard deviation. Hmm, I'm thinking C is the answer here.
