QUESTION 1 Sample data for the total sales credited to a sales representative, the number of accounts he/she manages and whether there has been an increase or decrease in the market share over the previous four years (lncrease=1, Decrease=0) were collected with the purpose to create a model that can be use to predict the total sales. The following tables show the output obtained when fitting a linear model. DF Sum Square Mean Square F P Value Regression 3 8844.846 2948.282 7.769 0.001 Error 21 7969.842 379.516 Total 24 16814.688 Coefficients Standard Errors T Statistic P Value Intercept 35.286 7.374 4.785 0 :cAcmum 0.184 0.049 3.788 0.001 .20th 30.392 7.794 3.899 0.001 1. State the population model. 2. State the least square estimated equations. 3. Provide the intepretation of the coefficients of the model. 4. Use alpha = 0.09 . Which independent variables have a significant relationship with the level of sales? 5. Test the overall significance of the model. State your conclusion. Use alpha: 0.09 6. Does this model provide a good fit to the data. Justify your answer. '1' T I Arial v 3(12pt) v T . : . '2' C; (:3 l3 3: 3 n v x l Path: p Wordszo A
