Instructions: The
questions are all mandatory. Documents are not allowed. Ten experiments (only four are reported here) were done to find the link between sales volumes and bonus rates paid to the sales team in specific months. 1 4 2 3 Month 0 1 3 4 Bonus (%) 4 8 3 10 Sales (in 00s) 1. According to you, which variable should be the dependent one? Explain your answer. 2. Draw a scatter diagram of sales volumes and bonus rates. Interpret it. 3. Find the equation for the line of best fit through the data. Do not forget to write down the estimated equation. Provide a table containing the underlying calculations. 4. Interpret the coefficients obtained in the
question (3). 5. Present the analysis of variance. 6. What can you tell us about the quality of the regression? 7. Which sales volume could one expect with a 10% bonus? 1
8. Another model has been proposed by your classmate, with parameters a =0.7 and b=-1.2. Forecast the regressand y for periods 1 - 5. 9. Tell us which forecasting method you find better in this exercise. Justify your choice. 2.
