Consider the following time series:
| Quarter | Year 1 | Year 2 | Year 3 |
| 1 | 66 | 63 | 57 |
| 2 | 48 | 40 | 50 |
| 3 | 59 | 61 | 54 |
| 4 | 73 | 76 | 67 |
Use a multiple linear 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. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (Example: -300)
