A normally distributed error term with mean of zero would Group of answer choices have values that are symmetric about the variance. allow more accurate modeling. yield biased regression estimates. be a hyperbolic curve.

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.

It is correct, in this case we would have a more accurate model.

c. yield biased regression estimates.

it is also false, not necessarily.

d. be a hyperbolic curve.

false, not necessarily.

a. she will receive a refund of $278.

step-by-step explanation:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
