Please answer the following question with regards to MATLAB software:

Question 5 Suppose the Random Bank is now offering 9% interest on balances of less than $5000, 12% for balances of $5000 or more but less than $10000 and 15% for balances of $10000 or more. Calculate or evaluate a customers new balance after one year given the initial balance as $1500 multiplied by a random number.

Answer the following question with regards to STELLA Software

Question 6 a) With the aid of examples outline common mistakes in System Dynamics modelling. [6] b) Identify each element as either stock, flow or constant and label its unit of measurement. Take each stock and determine its inflow and outflows (Mature trees, Planting, Time for saplings to mature, Saplings, Harvesting and Maturing). [12] c) Assign link polarities to the given causal loop diagram below. [7] General Modelling and Simulation SECTION Question 8 a) Define empirical models. [3] b) Describe the use of models in simulation. [4] c) Describe briefly the steps involved in a simulation study. [12] d) With the aid of examples, explain the process of verification and validation in modelling processes. [8] e) Give any four advantages of using modelling and simulation in decision-making.
