Would you use the model to make forecasts for future years? The model doesn't appear to provide a good fit to the data. The model is under predicting sales and doesn't have enough slope the last couple years. I would not use this model for making predictions. 40000 35000 30000 25000 20000 15000 10000 5000 2012 2014 2016 2018 2020 2024 2026 2028 Sales -Forecast Page: 1 of 4 73°F Sunny Q Search QMM2410 W24 Chp 17 HW problems Ο Solution 品起 1 4 << > Q ENG 12:40 PM 4/14/2024 PRE Styles Sensitivity Add-ins F15 × ✓ fx A B C D E F G H | J K 1 2013 2800 2 2014 3577 3 2015 3139 4 2016 8469 5 2017 7331 6 2018 10972 7 2019 13573 8 2020 22634 9 2021 15077 10 2022 31430 11 2023 38524 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28
