Extracted text: Graph (ii) What type of pattern exists in the data? Is there an indication of a seasonal pattern? Horizontal pattern, with seasonality (b) Use a multiple linear regression model with dummy variables as follows to develop an equation to account for seasonal effects in the data: Qtri = 1 if quarter 1, 0 otherwise; Qtr2 = 1 if quarter 2, 0 otherwise; Qtr3 = 1 if quarter 3, 0 otherwise. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (Example: -300) Qtri + Qtr2 + Qtr3 (c) Compute the quarterly forecasts for next year. Year Quarter Ft 4 4 2 4 3 4.
