CASE STUDY \#3: CURVE FITTING (Engineering Product Sales Model) Problem Statement As an engineer with the Ultimate Company you are provided with the following measured data: Figure 1. Number of Computers on the Market versus Time. What to do 1. Examine and study the data carefully. Enumerate your inferences from the data 2. Use trend analysis and extrapolation techniques to make predictions at days 55,65 and 90 . Document your results as shown in Table 2 below: Table ? 3. Plot second-order and third-order regression curves on same \# computers vs. time axes 4. Plot interpolation and extrapolation curves on same \# computers vs. time axes 5. Be as creative as you can with this project above and beyond the main requirements of this study. 6. Discuss your results Table 2: Results of fitting various interpolating and least-squares polynomials to the data of Table 1. An interpolation at t=55 and extrapolation at t=65 and 90 are shown
