Yajvin built the following regression equation for forecasting Sales of Vins Dairy. Sales = 125 + 21 Q1 + 45 Q2 - 76 Q3 + 12 T + 201 D Where Sales is the sales in Rs. Million, Q1, Q2 and Q3 are dummy variables representing Quarters 1, 2 and 3 respectively, T is the time trend with 1 representing the first year, 2 representing the second year and so on. The dairy has switched to organic in Year 8 and D is the dummy variable representing this organic initiative (coded as "0" for years 1 to 7, and "1" for all years after 7) Write the final regression equation for Quarter 4. Max score: 1 O A. Sales = 125 + 45 Q2 - 76 Q3 - 12 T + 201 D O B. Sales = 326 + 12 T O C. Sales = 125 + 12 T + 201 D O D. None of these
