Wait, zero mean? Isn’t that a bit odd?

I feel like I mixed up the assumptions last time. I know they need to be normally distributed, but I'm uncertain about the correlation aspect.

I remember something about errors having zero mean and constant variance, but I can't recall if they should be correlated or independent.

I think the errors should be independent and normally distributed, but I'm not sure about the mean and variance part.
