nfo K The Wellington company wants to develop a simple linear regression model for one of its products. Use the following 12 periods of historical data to develop the regression equation and use it to forecast the next three periods. Click the icon to view the historical data for the previous 12 periods. The simple linear regression line is F₁ = + x₁. (Enter your responses rounded to two decimal places and include a minus sign if necessary.)
