Consider the following time series data. Quarter 1 2 3 4 (1) (11) Year 1 (iv) 4 W 2 3 5 (a) Choose the correct time series plot. (1) Year 2 Moe L 6 3 5 7 - Select your answer - What type of pattern exists in the data? Select your answer - Year 3 7 6 6 8 Time Period Q1 Quarer 1 Qurve 2 Q1 Quar YL (b) Use a multiple regression model with dummy variables as follows to develop an equation to account for seasonal effects in the data: Qtr11 if Quarter 1, 0 otherwise; Qtr2 = 1 if Quarter 2, 0 otherwise; Qtr3= 1 If Quarter 3, 0 otherwise. 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). If the constant is "1" it must be entered in the box. Do not round intermediate calculation. Qtrl + Qtr2 + 9= Qtr3
