Observations are taken on sales of a certain mountain bike in 24 sporting goods stores. The regression model was Y= total sales (thousands of dollars), X1 = display floor space (square meters), X2 = competitors' advertising expenditures (thousands of dollars), X3 = advertised price (dollars per unit). (a) Fill in the values in the table given here. (Negative values should be indicated by a minus sign. Leave no cells blank - be certain to enter "O" wherever required. Round your t-values to 3 decimal places and p-values to 4 decimal places.) Predictor Coefficient SE tcalc p-value Intercept FloorSpace Competing Ads Price 1,254.2 300.2 11.318 1.69 -6.260 3.999 -e.14748 0.08280 (b-1) What is the critical value of Student's tin Appendix D for a two-talled test at a = 017 (Round your answer to 3 decimal places.) tvalue = (b-2) Choose the correct option.
