Not sure about that, could it be B instead?

The mean is 2.8, so variance should be low.

I vaguely recall that the variance is the average of the squared differences from the mean. I hope I remember the steps correctly!

I feel like the variance should be pretty small since the numbers are so close together. Maybe option B or D could be right?

I think I saw a similar question where we had to find variance from a small data set. I might lean towards option D, but I need to double-check my calculations.

I remember we practiced calculating variance, but I'm not sure if I should use the sample or population formula here.

Wait, what? I'm totally lost on this one. Variance? Deviations? I don't even know where to start. This is going to be a tough one for me.

I've got this! Variance is just the average of the squared differences from the mean. I'll crunch the numbers and see which answer choice matches.

Okay, let's think this through step-by-step. I'll need to calculate the mean, then the deviations from the mean, square those deviations, and finally take the average of the squared deviations to get the variance.

Hmm, this looks tricky. I'm not sure I remember the exact formula for variance. Maybe I should review my notes quickly before attempting this.

Based on my understanding of how Dynamics 365 Business Central handles payment terms, the Due Date field is the one used to calculate the payment due date. I'll select B.

Variance? More like nightmarish mathematical torture. I should have studied statistics harder in college. Oh well, time to wing it!

Wait, is this a trick question? I'm pretty sure the answer is not A or C, those values seem way off. B or D, that's my guess.
