3	175	255	326	384	460
4	13	36	48	82	196

Use Excel Solver to find the coefficients of a multiple regression model with dummy variables as follows to develop an equation to account for seasonal effects in the data. Qtr1 = 1 if Quarter 1, 0 otherwise; Qtr2 = 1 if Quarter 2, 0 otherwise; Qtr3 = 1 if Quarter 3, 0 otherwise. Round your answers to two decimal places.

F_t = + Qtr1 + Qtr2 + Qtr3
Let Period = 1 to refer to the observation in Quarter 1 of year 1; Period = 2 to refer to the observation in Quarter 2 of year 1; . . . and Period = 20 to refer to the observation in Quarter 4 of year 5. Using the dummy variables defined in part (b) and Period, develop an equation to account for seasonal effects and any linear trend in the time series using Excel Solver. Round your answers to two decimal places. If your answer is negative value enter minus sign.

F_t =  + Qtr1 + Qtr2 + Qtr3 + Period

Based upon the seasonal effects in the data and linear trend, compute estimates of quarterly sales for year 6. Round your answers to one decimal place.
