**Question 1**

Management science techniques focus primarily on observation, model construction and implementation to find an appropriate solution to a problem.

**Question 2**

In linear programming problems, multiple optimal solutions occur when constraints are parallel to each other.

**Question 3**

A change in the value of an objective function coefficient will always change the value of the optimal solution.

**Question 4**

Fractional relationships between variables are not permitted in the standard form of a linear program.

**Question 5**

In a total integer model, all decision variables have integer solution values.

**Question 6**

In a transshipment problem, items may be transported from destination to destination and from source to source.

**Question 7**

The events in an experiment are mutually exclusive if only one can occur at a time.

**Question 8**

The minimax criterion minimizes the maximum payoff.

**Question 9**

Excel can be used to simulate systems that can be represented by both discrete and continuous random variables.

**Question 10**

Adjusted exponential smoothing is an exponential smoothing forecast adjusted for seasonality.
