allow more accurate modeling
Step-by-step explanation:
They ask us what we should expect from a normally distributed error term with of zero, we analyze each option:
a. have values that are symmetric about the variance.
False, does not guarantee symmetry.
b. allow more accurate modeling.

c. yield biased regression estimates.
it is also false, not necessarily.
d. be a hyperbolic curve.
false, not necessarily.
