I'm thinking it is sigma squared. Mainly because all the other 2 fractions share the same denominator. It seems weird if it is not.Why do think it isn't sigma squared?
I think you're saying that what you wrote is what your professor wrote, not your own work.I have no idea why my professor left sigma for this fraction but all the other ones have sigma squared.
