The linear trend forecasting equation for an annual time series containing 39 values (from 1968 to 2006) on net sales (in billions of dollars) is shown below. Complete (a) through (e) below. Y; = 4.6 +0.8%; C. a. Intepret the Y-intercept, bo. Which statement below is the interpretation of the Y-intercept? O A. The Y-intercept bo = 4.6 indicates that sales are predicted to increase by 54.6 billion/year. OB. The Y-intercept bo = 0.8 reflects the predicted net sales in 1968. O C. The Y-intercept bo = 0.8 indicates that sales are predicted to increase by $0.8 billion/year. D. The Y-intercept bo = 4.6 reflects the predicted net sales in 1968. b. Intepret the slope, by. Which statement below is the interpretation of the slope? O A. The slope by = 4.6 indicates that sales are predicted to increase by $4.6 billion/year. OB. The slope by = 0.8 reflects the predicted net sales in 1968. C. The slope by = 0.8 indicates that sales are predicted to increase by $0.8 billion/year. OD. The slope by = 4.6 reflects the predicted net sales in 1968. c. What is the fitted trend value for the ninth year? $1 billion (Simplify your answer.)
