Answer to Question 1

b
RATIONALE: The reduced cost indicates the change in the optimal objective function value that results from changing the right-hand side of the nonnegativity constraint from 0 to 1.

Answer to Question 2

d
RATIONALE: Central Limit Theorem states: In selecting random samples of size n from a population, the sampling distribution of the sample mean can be approximated by a normal distribution as the sample size becomes large.
