Suppose we have the following annual sales data for an automobile dealership:
Year Sales Trend
2009 121 1

2018 231 10
We want to forecast sales for 2019 and 2020 using either a simple trend model or a quadratic trend model. Use a within sample forecasting technique to determine the best model using the RMSE measure discussed in lecture. Once this model has been determined, provide actual forecasts for 2019 and 2020. Report the two RMSE values, along with the actual forecasts. Submit your Excel file used to create these answers.

Cameron Bly is a sales manager for an automobile dealership. He
earns a bonus each year based on revenue from the number of autos
sold in the year less related warranty expenses. Actual warranty
expenses have varied over the prior 10 years from a low of 3% of an

tended to estimate warranty expenses on the high end to be
conservative. He must work with the dealership’s...
