A linear model for the data is F(t) 9.44t+84.182. = 220 210- 200- 190- 180- 170- 160- 150 140- 130- 120- 110 100- 90 807 12 Use the above scatter plot to decide whether the linear model fits the data well. The function is a good model for the data. The function is not a good model for the data Estimate the retails sales in the U. S. in 2015. billions of dollars. Use the model to predict the year that corresponds to retails sales of $249 billion.
