There appears to be a seasonal pattern in the data and perhaps a |upward linear trend V U.b. Use the following dummy variables to develop an estimated regression equation to account for any 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 ( thousands of dollars) to whole number. Revenue = 70 + -100 Qtrl + 105 & Qtr2 + 245 Qtr3 Based only on the seasonal effects in the data, compute estimates of quarterly sales for year 6. Round your answers to whole number. Quarter 1 forecast $ 227 thousands Quarter 2 forecast $ 322 * thousands Quarter 3 forecast $ 463 thousands Quarter 4 forecast $ 218 x thousands c. 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 3. Using the dummy variables defined in part (b) and Period, develop an estimated regression equation to account for seasonal effects and any linear trend in the time series. Round your answers (in thousands of dollars) to whole number. Enter negative value as negative number. The regression equation is: Revenue = -70 + 45 Qtrl + 128 Qtr2 + -257 Qtr3 + 12 Period Based upon the seasonal effects in the data and linear trend, compute estimates of quarterly sales for year 6. Round your answers to whole number. Quarter 1 forecast $ 40 thousands Quarter 2 forecast $ 44 thousands Quarter 3 forecast $ 49 X thousands Quarter 4 forecast $ -67 thousandsHudson Marine provides boats sales, service, and maintenance.
