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.
