Consider the following time series data. (a) Choose the correct time series plot. (b) Use a muitiple regression model with dummy variables as foliows to develop an equation to accolunt for seasonal effects in the data: Qtr1 a 1 if Quarter 1 , 0 otherwise, Qtre =1 if Qusrter 2, 0 otherwitie; Qtr3 =1 if Quarter 3, 0 otherwise. If recuired, 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 ), if the constant is " 1 " it must be entered in the box. Do not round intermedate calculation. = (c) Compute the quarterly forecasts for hext year based on the model you developed in part (b). If required, round your answers to three decimal places. Do not round intermediate calculation. Consider the following time series data. (a) Choose the correct time series plot.
