(i) (ii) Quarterly Revenue (i) Quarterly Revenue (ii) Quarterly Revenue (iii) Quarterly Revenue Quarterly Revenue (b) Use a multiple regression model with dummy variables as follows to develop on equation to account for seasonal effects in the data: Qtr 1 . 1 if quarter 1,0 otherwise; Qtr2 =1 if quatter 2,0 otherwise; Q tr 3=1 if quarter 3,0 otherwise. Revenue = (c) Based on the model you developed in part (b), compute estimates of quarterly sales for year 6. (d) Let Period =1 refer to the observation in quarter 1 of year 1 ; Period =2 refer to the observation in quarter 2 of year 1 ;... and Period =20 refer to the observation in quarter 4 of year 5 . Using the dummy variables defined in part (b) and the variable Period, develop an equation to account for seasonal effects and any linear trend in the time series. If required, round your answers to three decimal places. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank (Example: -300 ) Revenue=QQu1+Qtr
