A global minimum
 a. is also a local maximum.
  b. need not be a local maximum, but vice versa is true.
  c. is also a local minimum.
  d. need not be local minimum, but vice versa is true.

Question 2

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

Answer to Question 1

c
RATIONALE: A global minimum is also a local minimum.

Answer to Question 2

b
RATIONALE: The practical implication of normally distributed errors with a mean of zero and a constant variation for any given combination of values of x1, x2, . . . , xq is that the regression estimates are unbiased, possess consistent accuracy, and tend to err in small amounts rather than in large amounts.
