The linear trend forecasting equation for an annual time series containing 45 values (from 1960 to 2004) on net sales (in billions of dollars) is shown below. Complete (a) through (e) below. Y = 3.1 + 0.6X; a. Intepret the Y-intercept, bo. Which statement below is the interpretation of the Y-intercept? O A. The Y-intercept bo = 3.1 reflects the predicted net sales in 1960. O B. The Y-intercept bo = 3.1 indicates that sales are predicted to increase by $3.1 billion/year. O C. The Y-intercept bo = 0.6 indicates that sales are predicted to increase by $0.6 billion/year. O D. The Y-intercept bo = 0.6 reflects the predicted net sales in 1960
