Question 4 Scaling problems: O can cause Analytic Solver Platform to consider a linear problem as nonlinear. O can cause problems in accuracy of solutions returned. O are caused by small numbers and large numbers used in the same problem. O all of these.Question 5 Which of the following describes Data Envelopment Analysis (DEA)? O DEA finds the most effective company among some set of companies. O DEA determines if a company is converting inputs to outputs as effectively as possible. O DEA determines how effective a company converts inputs to outputs compared to other companies. O DEA compares how effective a company converts inputs to outputs compared to a benchmark composite of all companies.Question 6 Data Envelopment Analysis (DEA) is an LP-based methodology in which weighted sums of inputs and outputs are calculated and: O the constraints capture the maximum effectiveness of each unit. O the objective is to maximize every units output. O the constraints ensure the sum of the weighted outputs is one. O the objective for each unit is to maximize the weighted sum of its outputs.Question 7 Using Data Envelopment Analysis (DEA) for an inefficient unit, a more efficient composite unit can be found by O Solving its DEA problem and retrieving the weights from the answer report. O Solving its DEA problem and examining those units whose final value is non-zero. O Solving its DEA problem and using the resulting shadow prices as composite weights. O Solving its DEA problem and using the positive resulting shadow prices as composite weights
