A business analyst is hired by a local real estate firm to forecast how condo sales on a quarterly basis over the next several years. The firm provides the analyst with three years worth of quarterly condo sales data. Noticing that the data exhibits increasing trend and a seasonal pattern, the analyst chooses to create a multiple regression model for generating the forecasts: y = 130 + 16 OQtr1+(-98) Qtr2 + (-85) Qtr3 + 9 t In the equation above, Qtr1, Qtr2, and Qtr3 are dummy variables corresponding to the first, second, and third quarters of the calendar year and t is the time period number, starting with t = 1 for the first quarter of year 1. %3D Using the model described above, what is the forecast for the number of condo sales the firm can expect during the second quarter of year 5?
