Which of the following is true about the sensitivity analysis for integer optimization problems?
 a. Sensitivity reports are readily available for integer optimization problems similar to the linear programming problems.
  b. Because of the discrete nature of the integer optimization, Excel Solver takes much more time to calculate objective function coefficient ranges, shadow prices, and right-hand-side ranges.
  c. The sensitivity analysis is not important for integer problems.
  d. To determine the sensitivity of the solution to changes in model inputs for integer optimization problems, the data must be changed and the problem must be re-solved.

Question 2

Statistical significance at the 0.01 level is___________ than significance at the 0.05 level .
 a. more difficult to achieve
  b. easier to achieve
  c. less costly
  d. less informative

Answer to Question 1

d
RATIONALE: Sensitivity reports are not available for integer optimization problems. To determine the sensitivity of the solution to changes in model inputs, you must change the data and re-solve the problem.

Answer to Question 2

a
RATIONALE: Significance at the 0.01 level of significance is more difficult to achieve than the 0.05 level of significance because it requires a great deal of evidence against the null hypothesis.
