Consider the following time series data.

Please refer to picture.

Use a multiple 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. 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)

Value = __________  + ____________  Qtr1 + ____________  Qtr2 + ___________  Qtr3 +______________  t
Compute the quarterly forecasts for next year. If required, round your answers to two decimal places.

Quarter 1 forecast = 

Quarter 2 forecast = 

Quarter 3 forecast = 

Quarter 4 forecast = 

This table presents quarterly data over a three-year period. It records values corresponding to each year by quarter. - **Quarter 1:** - Year 1: 4 - Year 2: 6 - Year 3: 7 - **Quarter 2:** - Year 1: 2 - Year 2: 3 - Year 3: 6 - **Quarter 3:** - Year 1: 3 - Year 2: 5 - Year 3: 6 - **Quarter 4:** - Year 1: 5 - Year 2: 7 - Year 3: 8 Each row represents a quarter of the year, while each column under "Year 1," "Year 2," and "Year 3" represents the value observed or recorded for that specific period. This breakdown allows for a comparative analysis of the data across different quarters and throughout the three-year span.
