# Electronics manufacturer SE must decide whether or not to invest in

the development of a new type of battery. If the development succeeds, the market for the battery may be large or small. If it doesn’t succeed, the development efforts may or may not generate minor innovations that would offset some of the battery’s development costs. The tree below summarizes the decision.

The EMV of developing the new battery is \$300,000. Based on EMV, SE should develop the battery. If the manager chooses not to develop the battery, which of the following best describes the manager’s attitude towards this decision?

Risk averse.
Risk neutral.
Risk seeking.
Cowardly.

1. Which of the following statements are FALSE (choose all the false statements. Choosing True statements will incur negative marking)
 Regression model is an example of a probabilistic and descriptive model In the problem solving process, once we test the results, we can directly implement the solution. Finding the basic statistics (like mean), correlation, drawing pivot tables and charts are examples of descriptive models. Models are simplified versions of a situation that we want to analyze/study. We only input variables that we can control in our model. Variables that we cannot control cannot be part of a decision model. Sensitivity analysis helps us find the optimal solution
